 The system clocks are generated by:
– Two fully programmable PLLs. One is used to generate a clock for CPU and
AMBA AHB bus and the other is used in case the DDR clock has to be different
(asynchronous) with respect to the CPU clock.
– One “high precision” clock synthesizer with 4 outputs providing different
frequencies for the various IPs
 Fully programmable control of the clock and reset signals for all the slave blocks
allowing sophisticated power management.

4.2 Shared I/O pins (MFIOs)

The 104 MFIOs can be configured in different modes. This allows the STreamPlug ST2100
to be tailored for various applications.
For the MFIO from 88 to 103, the signal specified in Table 16 is also conditioned by an
internal selection MUX that can choose among the specified signal and an internal basic
subsystem general purpose IO (BS_GPIO), as specified in the STreamPlug ST2100 manual
and shown in Figure 2 and Figure 3.

6 Clocking parameters

This section details clock related electrical specifications.

The external circuit for generating the clock from a crystal oscillator is shown in Figure 4.

1. CL1 and CL2 are the load capacitors.

The value of the capacitors depends on the type of the selected crystal. To calculate the
value of the load capacitance, use Equation 1.
For this example, an Aker C2E-24.000-12-3030-X 24 MHz oscillator has been used.
Load capacitance CL:

Equation 1
CL = (CL1 × CL2 / CL1 + CL2) + CS
Where CL1 and CL2 are the load capacitors and CS is the circuit's stray capacitance.
In our application this implies:

Equation 2
CL1 = CL2 = Cext

Equation 3
Cext = (CL - CS) × 2
Example
For the Aker® C2E-24.000-12-3030-X crystal:
CL = 12 PF; with CS = 3 PF, Cext = CL1 = CL2 = 18 PF.
Note: The ESR of the used quartz must be < 50 .

1. CL1 and CL2 are the load capacitors.

The value of the capacitors depends on the type of the selected crystal. For example, using
a FOX Electronics®, P/N NC26LF-327 32.768 KHz oscillator, the value of the capacitors is
15 pF. The oscillator may not start if a crystal (FOX P/N FX325BS) is used.
If the shunt capacitance (Co) of the crystal is ~ 7.0 pF, then the maximum ESR of the crystal
must be less than 50 .

6.3 PCIe/SATA clock

For SATA operation, the PCIE_XTAL1/PCIE_XTAL2 clock inputs can be implemented by
a 30 MHz crystal oscillator as shown in Table 18.
For PCIe operation, a suitable clock driver such as IDT IDT_9FG104 can be used.

7 Electrical characteristics

This section provides electrical specifications for the STreamPlug ST2100 device.

7.1 Absolute maximum ratings

This product contains devices to protect the inputs against damage due to high/low static
voltages. However it is advisable to take normal precaution to avoid application of any
voltage higher/lower than the specified maximum/minimum rated voltages.
The absolute maximum ratings shown in Table 19 are the maximum stress that can be
applied to a device without causing permanent damage. However, extended exposure to
minimum/maximum ratings may affect long term device reliability.

TJ Junction temperature -40 125 °C

7.2 Power consumption

In Table 20 and Table 21 power consumption data are based on bench measurements with
devices using the Linux OS, the CPU and DDR2 running at 333 MHz and all on-chip
peripherals and internal modules enabled while the STreamPlug ST2100 is transferring
a file from the USB Flash memory to the powerline.

Thermal simulations should be done to verify if additional cooling is required. These

simulations should take into account power consumption, PCB dissipation, air flow and/or
heatsinks. The STreamPlug device can perform correctly above the specified ambient
temperature range if the maximum junction temperature remains below 125 °C.

a time interval of 2 ms, which is the start-up time of the main oscillator, as illustrated in

1. The total profile height (dim. A) is measured from the seating plane to the top of the component.
The maximum total package height is calculated by the following methodology:
A1 typ. + A2 typ. + A3 typ. +  (A12 + A22 + A32 tolerance values).
Thin profile: 1.00 < A . 1.20 mm / fine pitch: e < 1.00 mm pitch.
2. The typical ball diameter before mounting is 0.30 mm.
3. The tolerance of position that controls the location of the pattern of balls with respect to datums A and B.
For each ball there is a cylindrical tolerance zone “eee” perpendicular to datum “C” and located on true
position with respect to datums “A” and “B” as defined by “e”. The axis perpendicular to datum “C” of each
ball must lie within this tolerance zone.
4. The tolerance of position that controls the location of the balls within the matrix with respect to each other.
For each ball there is a cylindrical tolerance zone “fff” perpendicular to datum “C” and located on true
position as defined by “e”. The axis perpendicular to datum “C” of each ball must lie within this tolerance
zone. Each tolerance zone “fff” in the array is contained entirely in the respective zone “eee” above. The
axis of each ball must lie simultaneously in both tolerance zones.

The TFBGA (“Thin profile Fine Pitch Ball Grid Array”) package uses a grid of solder balls as
its connectors. The TFBGA package is noted for its compact size, high lead count and low
inductance, which allows lower voltages to be used.
