Note:
1. All multiplexed signals are listed only once and do not reoccur.
2. It is recommended that a weak pull-up resistor (2–10 KΩ) be placed on this pin to OVDD.
3. Open drain signal. GPIO pins may be programmed to operate as open-drain outputs.
4. This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the
reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. If the signal is
intended to be high after reset and if there is any device on the net which might pull down the value of the net at reset, a pullup
or active driver is needed.
5. The value of LA[29:31] during reset sets the CCB clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
resistors.
6. The value of LALE, LGPL[02], LBCTL at reset set the e500 core0 clocks to CCB Clock PLL ratios. These pins require 4.7-kΩ
pull-up or pull-down resistors.
7. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or
because it has other manufacturing test functions. This pin is therefore described as an I/O for boundary scan.
8. If this pin is configured for local bus controller use, pull up with 2–10 KΩ resistor to BVDD to ensure there is no random chip
select assertion due to possible noise or other causes.
9. This output is actively driven during reset rather than being three-stated during reset.
10. These JTAG pins have weak internal pull-up P-FETs that are always enabled.
11. If this pin is connected to a device that pulls down during reset, an external pull-up is required to drive this pin to a high state
during reset.
12. Do not connect.
13. Independent supply derived from board VDD.
14. It is recommended that a pull-up resistor (~1 kΩ) be placed on this pin to OVDD.
15. The following pins must NOT be pulled down during power-on reset: DMA1_DACK[00], LA[17], USB_STP, TSEC2_TXD[06],
HRESET_REQ, MSRCID[2:3], MDVAL, ASLEEP.
16. TSEC2_TXD[05] is a POR configuration pin for eSDHC card-detect (cfg_sdhc_cd_pol_sel), and it also has an alternate
function of TSEC3_TX_EN. When eTSEC1 or eTSEC2 or eTSEC3 are used as parallel interfaces, the TSECx_TX_EN pins
require an external 4.7-k pull-down resistor to prevent PHY from seeing a valid Transmit Enable before it is actively driven.
However, the pull-down resistor on TSEC3_TX_EN causes the eSDHC card-detect (cfg_sdhc_cd_sel) to be inverted; the
inversion should be overridden from the SDHCDCR[CD_INV] debug control register. If the device is configured to boot from
the eSDHC interface, the SDHC_CD should be inverted on the board.
17. TSEC2_TXD[01] is used as cfg_dram_type. It must be valid at power up.
18. For DDR2 MDIC[00] is grounded through an 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1% resistor
and MDIC[01] is connected to GVDD through an 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1%
resistor. These pins are used for automatic calibration of the DDR IOs. The calibration resistor value for DDR3 must be 20-Ω
(full-strength mode), or 40.2-Ω (half-strength mode).

19. DDRCLK input is only required when the P2010 DDR controller is running in asynchronous mode. See Section 4.2.2, “Clock
Signals”, Section 4.4.3.2, “DDR PLL Ratio” and Table 4-10, “DDR Complex Clock PLL Ratio,” in the P2020 QorIQ Integrated
Communications Host Processor Family Reference Manual
20. EC_GTX_CLK125 is a 125-MHz input clock shared among all eTSEC ports in the following modes: GMII, TBI, RGMII and
RTBI. If none of the eTSEC ports is operating in these modes, the EC_GTX_CLK125 input can be tied off to GND. The
EC_GTX_CLK125 signal high level is nominally LVDD.
21. These POR configuration inputs may be used in the future to control functionality. It is advised that boards are built with the
ability to pulldown these pins.LA[20:22], UART_SOUT[00], MSRCID[01], MSRCID[04], and DMA1_DDONE[00] are reserved
for future reset configuration.
22. Incorrect settings can lead to irreversible device damage.
23. The value of LAD[0:15] during reset sets the upper 16 bits of the GPPORCR as a user option setting.
24. Used to set the DDR clock PLL settings; requires a 4.7-kΩ pull-up or pull-down resistor.
25. Used to determine CPU boot configuration; requires a 4.7-kΩ pull-up or pull-down resistor.
26. Pin must be the same voltage as VDD.
27. SD_IMP_CAL_RX is grounded through an 200-Ω precision ±1% resistor and SD_IMP_CAL_TX is grounded through an
100-Ω precision ±1% resistor.
30. Requires a pull down with 100~1K to GND
31. 100K pull down needed if this signal is used as a CD pin for SD cards. The pull down is not needed for MMC cards.
32. All unused MCK pins must be disabled via DDRCLKDR register.
33. This pin requires a 1 kΩ pull up to OVDD.
34. For systems that boot from local bus (GPCM)-controlled NOR flash or (FCM)-controlled NAND flash, a pullup on LGPL4 is
required.
35. These pins may be connected to a thermal diode monitoring device such as the ADT7461A. If a thermal diode monitoring
device is not connected, these pins may be connected to test point or left as a no connect.
36. This pin, if not used, must be pulled high or low via individual 2–10 kΩ resistor.
37. This pin must be pulled high or low via a 2–10 kΩ resistor.
2 Electrical Characteristics
This section provides the AC and DC electrical specifications for the device. The device is currently targeted to these
specifications. Some of these specifications are independent of the I/O cell, but are included for a more complete reference.
These are not purely I/O buffer design specifications.
DUART, system control and power management, I2C, GPIOx8, OVDD –0.3 to 3.63 V 3
and JTAG I/O voltage
Enhanced local bus I/O voltage and GPIOx8 voltage BVDD –0.3 to 3.63 V 3
–0.3 to 2.75
–0.3 to 1.98
DUART, SYSCLK, system control and power OVIN –0.3 to (OVDD + 0.3) V 3
management, I2C, and JTAG signals
Notes:
1. Functional operating conditions are given in Table 3. Absolute maximum ratings are stress ratings only, and functional
operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent
damage to the device.
2. AVDD is measured at the input to the filter and not at the pin of the device.
3. Caution: (B,M,L,O,C, X)VIN must not exceed (B,G,L,O, C,X)VDD by more than 0.3 V. This limit may be exceeded for a
maximum of 20 ms during power-on reset and power-down sequences.
4. (M,L,O)VIN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 7.

Note:
1. tCLOCK refers to the clock period associated with the respective interface:
For I2C and JTAG, tCLOCK references SYSCLK.
For DDR, tCLOCK references MCLK.
For eTSEC, tCLOCK references EC_GTX_CLK125.
For eLBC, tCLOCK references LCLK.
For SerDes XVDD, tCLOCK references SD_REF_CLK.
The core voltage must always be provided at nominal 1.05 V (see Table 3 for actual recommended core voltage.) Voltage to the
processor interface I/Os are provided through separate sets of supply pins and must be provided at the voltages shown in Table 3.
The input voltage threshold scales with respect to the associated I/O supply voltage. OVDD and LVDD based receivers are simple
CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The SDRAM interface uses a differential receiver
referenced the externally supplied MVREF signal (nominally set to GVDD ÷ 2). The DDR DQS receivers cannot be operated in
single-ended fashion. The complement signal must be properly driven and cannot be grounded.
Note:
1. The drive strength of the DDR2/3 interface in half-strength mode is at TJ = 105 °C and at GVDD (min).
NOTE
While VDD is ramping, current may be supplied from VDD through the device to GVDD.
Nevertheless, GVDD from an external supply should follow the sequencing described
above.
From a system standpoint, if any of the I/O power supplies ramp prior to the VDD core
supply, the I/Os associated with that I/O supply may drive a logic one or zero during power

concerns, and the device is compatible with spread spectrum sources if the recommendations listed in Table 9 are observed.
Table 9. SYSCLK Spread Spectrum Clock Source Recommendations
At recommended operating conditions. See Table 3.
Note:
1. SYSCLK frequencies resulting from frequency spreading, and the resulting core and VCO frequencies, must meet the
minimum and maximum specifications given in Table 8.
2. Maximum spread spectrum frequency may not result in exceeding any maximum operating frequency of the device
CAUTION
The processor’s minimum and maximum SYSCLK, core, and VCO frequencies must not
be exceeded regardless of the type of clock source. Therefore, systems in which the
processor is operated at its maximum rated e500 core frequency should avoid violating the
stated limits by using down-spreading only.

noise on MVREF may not exceed the MVREF DC level by more than ±1% of GVDD (for example, ±18 mV).
3. VTT is not applied directly to the device. It is the supply to which far end signal termination is made and is expected to be

Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that
is captured with MDQS[n]. This must be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW.This can be
determined by the following equation: tDISKEW = ± (T ÷ 4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is the
absolute value of tCISKEW.

At recommended operating conditions (see Table 3).
Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing
(DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). For example,
tDDKHAS symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs
(A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference
(K) goes low (L) until data outputs (D) are invalid (X) or data output hold time.
2. All MCK/MCK and MDQS/MDQS referenced measurements are made from the crossing of the two signals.
3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS.
4. Note that minimum data rate for DDR3 is 667 MHz.
5. tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD) from the
rising edge of the MCK[n] clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control of the
MDQS override bits (called WR_DATA_DELAY) in the TIMING_CFG_2 register. This is typically set to the same delay as in
DDR_SDRAM_CLK_CNTL[CLK_ADJUST]. The timing parameters listed in the table assume that these two parameters
have been set to the same adjustment value. See the P2010 QorIQ Reference Manual for a description and understanding
of the timing modifications enabled by use of these bits.
6. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC
(MECC), or data mask (MDM). The data strobe must be centered inside of the data eye at the pins of the microprocessor.

NOTE
For the ADDR/CMD setup and hold specifications in Table 25, it is assumed that the clock
control register is set to adjust the memory clocks by ½ applied cycle.

SPI inputs—Master data (internal clock) input setup time tNIIVKH 5.75 — ns 4
Notes:
1. Output specifications are measured from the 50% level of the CLK to the 50% level of the signal. Timings are measured at
the pin.
2. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tNIKHOV symbolizes the NMSI
outputs internal timing (NI) for the time tSPI memory clock reference (K) goes from the high state (H) until outputs (O) are
valid (V).
3. The greater of the two output timings for tNIKHOX and tNIKHOV are used when the SPCOM[RxDelay] bit of eSPI Command
Register is set. For example, the tNIKHOX is 3.0ns and tNIKHOV is 10ns if SPCOM[RxDelay] is set.
4. For Windbond Flash dual-output mode both SPI_MOSI and SPI_MISO are inputs.
Output Z0 = 50 Ω CDVDD/2

Figure 13 represents the AC timing from Table 29. Note that although the specifications generally reference the rising edge of

as long as the minimum duty cycle is not violated and stretching occurs for no more than three tRGT of the lowest

Notes:
1. The symbols for timing specifications follow the pattern of t(First two letters of functional block)(signal)(state) (reference)(state) for inputs
and t(First two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tUSIXKH symbolizes USB timing (US)
for the input (I) to go invalid (X) with respect to the time the USB clock reference (K) goes high (H). Also, tUSKHOX symbolizes
USB timing (US) for the USB clock reference (K) to go high (H) with respect to the output (O) going invalid (X) or output hold
time.
2. All timings are in reference to USB clock.
3. All signals are measured from CVDD ÷ 2 of the rising edge of the USB clock to 0.4 × CVDD of the signal in question for 3.3 V
signaling levels.
4. Input timings are measured at the pin.
5. For active/float timing measurements, the high impedance or off state is defined to be when the total current delivered

6. When switching the data pins from outputs to inputs using the USB_DIR pin, the output timings is violated on that cycle
because the output buffers are tristated asynchronously. This should not be a problem, because the PHY should not be
functionally looking at these signals on that cycle as per ULPI specifications.

Figure 37 applies to all three controllers that eLBC supports: GPCM, UPM, and FCM.
For input signals, the AC timing data is used directly for all three controllers.
For output signals, each type of controller provides its own unique method to control the signal timing. The final signal delay
value for output signals is the programmed delay plus the AC timing delay. For example, for GPCM, LCS can be programmed
to delay by tacs (0, ¼, ½, 1, 1 + ¼, 1 + ½, 2, 3 cycles), so the final delay is tacs + tLBKHOV.

2. Open drain mode for MMC cards only.
Notes:
1. The symbols used for timing specifications herein follow the pattern of t(first three letters of functional block)(signal)(state)
(reference)(state) for inputs and t(first three letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tFHSKHOV
symbolizes eSDHC high speed mode device timing (SHS) clock reference (K) going to the high (H) state, with respect to the
output (O) reaching the invalid state (X) or output hold time. Note that, in general, the clock reference symbol representation
is based on five letters representing the clock of a particular functional. For rise and fall times, the latter convention is used
with the appropriate letter: R (rise) or F (fall).
2. In full speed mode, clock frequency value can be 0–25 MHz for a SD/SDIO card and 0–20 MHz for a MMC card. In high speed
mode, clock frequency value can be 0–50 MHz for a SD/SDIO card and 0–52 MHz for a MMC card.
3. CCARD ≤ 10 pF, (1 card), and CL = CBUS + CHOST + CCARD ≤ 40 pF
4. To satisfy setup timing, one way board routing delay between Host and Card, on SD_CLK, SD_CMD, and SD_DATx should
not exceed 0.65ns.

Notes:
1. The symbols used for timing specifications follow the pattern t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG device timing
(JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (K) going
to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input signals (D)
reaching the invalid state (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that in general, the clock
reference symbol representation is based on three letters representing the clock of a particular functional. For rise and fall
times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
2. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
3. All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question.
The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load. Time-of-flight delays
must be added for trace lengths, vias, and connectors in the system.

2.16 I2C
This section describes the DC and AC electrical characteristics for the I2C interfaces of the device.
Notes:
1. Note that the min VILand max VIH values are based on the respective min and max OVIN values found in Table 3.
2. Output voltage (open drain or open collector) condition = 3 mA sink current.
3. See the P2020 QorIQ Integrated Communications Host Processor Family Reference Manual for information on the digital
filter used.
4. I/O pins obstruct the SDA and SCL lines if OVDD is switched off.
Note:
1. The symbols used for timing specifications herein follow the pattern t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I2C timing (I2)
with respect to the time data input signals (D) reaching the valid state (V) relative to the tI2C clock reference (K) going to the
high (H) state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the START
condition (S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH
symbolizes I2C timing (I2) for the time that the data with respect to the STOP condition (P) reaches the valid state (V) relative
to the tI2C clock reference (K) going to the high (H) state or setup time.
2. The requirements for I2C frequency calculation must be followed. Refer to NXP application note AN2919, “Determining the
I2C Frequency Divider Ratio for SCL.”
3. As a transmitter, the device provides a delay time of at least 300 ns for the SDA signal (referred to as the VIHmin of the SCL
signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of a START or STOP
condition. When the device acts as the I2C bus master while transmitting, it drives both SCL and SDA. As long as the load
on SCL and SDA are balanced, the device does not generate an unintended START or STOP condition. Therefore, the 300
ns SDA output delay time is not a concern. If under some rare condition, the 300 ns SDA output delay time is required for the
device as transmitter, application note AN2919, referred to in note 2 above, is recommended.
4. The maximum tI2OVKL must be met only if the device does not stretch the LOW period (tI2CL) of the SCL signal.

external synchronous logic. GPIO inputs are required to be valid for at least tPIWID ns to ensure proper operation.

Figure 50 shows how the signals are defined. For illustration purposes, only one SerDes lane is used for description. Figure 50
shows the waveform for either a transmitter output (SD_TX and SD_TX) or a receiver input (SD_RX and SD_RX). Each signal
swings between A Volts and B Volts where A > B.
SD_TX or
SD_RX
A Volts
Vcm = (A + B)÷2
SD_TX or
SD_RX
B Volts
Using this waveform, the definitions are as follows. To simplify the illustration, the following definitions assume that the
SerDes transmitter and receiver operate in a fully symmetrical differential signaling environment:
Single-Ended Swing
The transmitter output signals and the receiver input signals SD_TX, SD_TX, SD_RX and SD_RX
each have a peak-to-peak swing of A – B Volts. This is also referred as each signal wire’s
Single-Ended Swing.
Differential Output Voltage, VOD (or Differential Output Swing)
The Differential Output Voltage (or Swing) of the transmitter, VOD, is defined as the difference of
the two complimentary output voltages: VSDn_TX – VSDn_TX. The VOD value can be either positive
or negative.
Differential Input Voltage, VID (or Differential Input Swing)
The Differential Input Voltage (or Swing) of the receiver, VID, is defined as the difference of the
two complimentary input voltages: VSDn_RX – VSDn_RX. The VID value can be either positive or
negative.
Differential Peak Voltage, VDIFFp
The peak value of the differential transmitter output signal or the differential receiver input signal
is defined as Differential Peak Voltage, VDIFFp = |A – B| Volts.
Differential Peak-to-Peak, VDIFFp-p
Since the differential output signal of the transmitter and the differential input signal of the receiver
each range from A – B to –(A – B) Volts, the peak-to-peak value of the differential transmitter
output signal or the differential receiver input signal is defined as Differential Peak-to-Peak
Voltage, VDIFFp-p = 2 × VDIFFp = 2 × |(A - B)| Volts, which is twice of differential swing in
amplitude, or twice of the differential peak. For example, the output differential peak-peak voltage
can also be calculated as VTX-DIFFp-p = 2 × |VOD|.
Differential Waveform
The differential waveform is constructed by subtracting the inverting signal (SD_TX, for example)
from the non-inverting signal (SD_TX, for example) within a differential pair. There is only one
signal trace curve in a differential waveform. The voltage represented in the differential waveform
is not referenced to ground. Refer to Figure 50 as an example for differential waveform.

a single-ended swing less than 800 mV and greater than 200 mV. This requirement is the same for both external
DC-coupled or AC-coupled connection.
— For external DC-coupled connection, as described in Section 2.18.2.2, “SerDes Reference Clock Receiver
Characteristics,” the maximum average current requirements sets the requirement for average voltage (common
mode voltage) to be between 100 mV and 400 mV. Figure 52 shows the SerDes reference clock input requirement
for DC-coupled connection scheme.

Figure 52. Differential Reference Clock Input DC Requirements (External DC-Coupled)
— For external AC-coupled connection, there is no common mode voltage requirement for the clock driver. Since
the external AC-coupling capacitor blocks the DC level, the clock driver and the SerDes reference clock receiver
operate in different command mode voltages. The SerDes reference clock receiver in this connection scheme has
its common mode voltage set to SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing
below and above the command mode voltage (SGND_SRDSn). Figure 53 shows the SerDes reference clock input
requirement for AC-coupled connection scheme.
—
Vcm
• Single-ended Mode
— The reference clock can also be single-ended. The SD_REF_CLK input amplitude (single-ended swing) must be
between 400 mV and 800 mV peak-peak (from VMIN to VMAX) with SD_REF_CLK either left unconnected or
tied to ground.
— The SD_REF_CLK input average voltage must be between 200 and 400 mV. Figure 54 shows the SerDes
reference clock input requirement for single-ended signaling mode.
— To meet the input amplitude requirement, the reference clock inputs might need to be DC or AC-coupled
externally. For the best noise performance, the reference of the clock could be DC or AC-coupled into the unused
phase (SD_REF_CLK) through the same source impedance as the clock input (SD_REF_CLK) in use.

3. Measured from –200 mV to +200 mV on the differential waveform (derived from SD_REF_CLK minus SD_REF_CLK). The
signal must be monotonic through the measurement region for rise and fall time. The 400 mV measurement window is
centered on the differential zero crossing. See Figure 55.
4. Measurement taken from single-ended waveform.
5. Matching applies to rising edge for SD_REF_CLK and falling edge rate for SD_REF_CLK. It is measured using a 200 mV
window centered on the median cross point where SD_REF_CLK rising meets SD_REF_CLK falling. The median cross point
is used to calculate the voltage thresholds that the oscilloscope uses for the edge rate calculations. The rise edge rate of
SD_REF_CLK must be compared to the fall edge rate of SD_REF_CLK, the maximum allowed difference should not exceed
20% of the slowest edge rate. See Figure 56.
6. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing.

Notes:
1. Specified at the measurement point and measured over any 250 consecutive UIs. The test load in Figure 58 must be used as
the Rx device when taking measurements. If the clocks to the Rx and Tx are not derived from the same reference clock, the
Tx UI recovered from 3500 consecutive UI must be used as a reference for the eye diagram.
2. Impedance during all LTSSM states. When transitioning from a fundamental reset to detect (the initial state of the LTSSM)
there is a 5 ms transition time before receiver termination values must be met on all unconfigured lanes of a port.
3. The Rx DC common mode impedance that exists when no power is present or fundamental reset is asserted. This helps
ensure that the receiver detect circuit does not falsely assume a receiver is powered on when it is not. This term must be

Maximum time TTX-EYE-MEDIAN- — — 0.15 UI Jitter is defined as the measurement variation of the
between the to-MAX-JITTER crossing points (VTX-DIFFp-p = 0 V) in relation to a recovered

and maximum consecutive unit intervals of sample data. Jitter is
deviation from measured using all edges of the 250 consecutive UI in the
the median. center of the 3500 UI used for calculating the TX UI. See

1. No test load is necessarily associated with this value.
2. Specified at the measurement point into a timing and voltage compliance test load as shown in Figure 58 and measured over

3. A TTX-EYE = 0.70 UI provides for a total sum of deterministic and random jitter budget of TTX-JITTER-MAX = 0.30 UI for the
Transmitter collected over any 250 consecutive Tx UIs. The TTX-EYE-MEDIAN-to-MAX-JITTER median is less than half of the total
Tx jitter budget collected over any 250 consecutive Tx UIs. It must be noted that the median is not the same as the mean. The
jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed to
the averaged time value.

Eye Width jitter that can be tolerated by the receiver can be
derived as TRX-MAX-JITTER = 1 – TRX-EYE = 0.6 UI.
See Notes 2 and 3.
Maximum time TRX-EYE-ME — — 0.3 UI Jitter is defined as the measurement variation of the
between the jitter DIAN-to-MAX- crossing points (VRX-DIFFp-p = 0 V) in relation to a
median and JITTER recovered TX UI. A recovered TX UI is calculated over
maximum 3500 consecutive unit intervals of sample data. Jitter
deviation from the is measured using all edges of the 250 consecutive UI
median. in the center of the 3500 UI used for calculating the
TX UI. See Notes 2, 3 and 4.
Notes:
1. No test load is necessarily associated with this value.
2. Specified at the measurement point and measured over any 250 consecutive UIs. The test load in Figure 58 must be used as
the Rx device when taking measurements. If the clocks to the Rx and Tx are not derived from the same reference clock, the
Tx UI recovered from 3500 consecutive UI must be used as a reference for the eye diagram.
3. A TRX-EYE = 0.40 UI provides for a total sum of 0.60 UI deterministic and random jitter budget for the Transmitter and
interconnect collected any 250 consecutive UIs. The TRX-EYE-MEDIAN-to-MAX-JITTER specification ensures a jitter
distribution in which the median and the maximum deviation from the median is less than half of the total. UI jitter budget
collected over any 250 consecutive Tx UIs. It must be noted that the median is not the same as the mean. The jitter median
describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged
time value. If the clocks to the Rx and Tx are not derived from the same reference clock, the Tx UI recovered from 3500
consecutive UI must be used as the reference for the eye diagram.
4. It is recommended that the recovered Tx UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm
using a minimization merit function. Least squares and median deviation fits have worked well with experimental and
simulated data.
All unit intervals are specified with a tolerance of ±100 ppm. The worst case frequency difference between any transmit and
receive clock is 200 ppm.

2.20.2 Equalization
With the use of high speed serial links, the interconnect media causes degradation of the signal at the receiver. Effects such as
Inter-Symbol Interference (ISI) or data dependent jitter are produced. This loss can be large enough to degrade the eye opening
at the receiver beyond what is allowed in the specification. To negate a portion of these effects, equalization can be used. The
most common equalization techniques that can be used are as follows:
• Pre-emphasis on the transmitter
• A passive high pass filter network placed at the receiver. This is often referred to as passive equalization.
• The use of active circuits in the receiver. This is often referred to as adaptive equalization.
Note:
1. Voltage relative to COMMON of either signal comprising a differential pair.

RefClk jitter.

Note:
1. Total jitter is composed of three components: deterministic jitter, random jitter, and single frequency sinusoidal jitter. The
sinusoidal jitter may have any amplitude and frequency in the unshaded region of Figure 60. The sinusoidal jitter component
is included to ensure margin for low frequency jitter, wander, noise, crosstalk and other variable system effects.

Enable before it is actively driven. TSEC2_TXD[05] is a POR configuration pin for eSDHC
card-detect (cfg_sdhc_cd_pol_sel) and also has an alternate function as TSEC3_TX_EN. When
using eTSEC3 as a parallel interface, the TSEC3_TX_EN requires a pull down. However,
because the pull-down resistor on TSEC2_TXD[05]/TSEC3_TX_EN signal causes the eSDHC
card-detect (cfg_sdhc_cd_pol_sel) to be inverted, the inversion must be overridden from the
SDHCDCR [CD_INV] debug control register.”

“TSEC2_TXD[05] is a POR configuration pin for eSDHC card-detect (cfg_sdhc_cd_pol_sel),
and it also has an alternate function of TSEC3_TX_EN. When eTSEC1 or eTSEC2 or eTSEC3
are used as parallel interfaces, the TSECx_TX_EN pins require an external 4.7-k pull-down
resistor to prevent PHY from seeing a valid Transmit Enable before it is actively driven. However,
the pull-down resistor on TSEC3_TX_EN causes the eSDHC card-detect (cfg_sdhc_cd_sel) to
be inverted; the inversion should be overridden from the SDHCDCR[CD_INV] debug control
register. If the device is configured to boot from the eSDHC interface, the SDHC_CD should be
inverted on the board.”
