I2C-BUS PROTOCOL
Addressing and data bytes
For programming the device (write mode) seven data byte registers are available; they are addressable via eight
subaddresses. Automatic subaddress incrementing enables the writing of successive data bytes in one transmission.
During power-on, data byte registers are reset to a default state by use of a Power On Reset (POR) circuit which signal
is derived from the internally generated I2C-bus supply voltage (V5OUT; pin 38). For reading from the device (read mode)
one data byte register is available without subaddressing.

Table 1 TDA9615H addresses and data bytes

Notes
1. Use of subaddress F0H to F7H (1111 0XXX) instead of 00H to 07H (0000 0XXX) disables the automatic subaddress
incrementing allowing continuous writing to a single data byte register.
2. The state of unused read bits are not reliable; their state may change during development.

Notes
1. X = don’t care.
2. Auto-normal function: if during hi-fi ‘playback’ mode no FM carrier is detected at FMIN (pin 37) the ‘Normal’ mode
audio signal (LININ; pin 21) is automatically selected by the output select function.
a) Hi-fi carrier detection time (i.e. auto-normal release time) can be selected via bit DETH:
‘fast’ mode: 1 to 2 HID periods (33 to 66 ms NTSC, 40 to 80 ms PAL)
‘slow’ mode: 7 to 8 HID periods (233 to 267 ms NTSC, 280 to 320 ms PAL).
b) The status of hi-fi detection can be monitored via the I2C-bus; see bit AUTN of the read byte (see Table 31).
c) If muting is required instead of automatic selection of the ‘Normal’ mode audio signal the normal input level
function should be set to mute; see bits NIL3 to NIL0 of the select byte.

Philips Semiconductors Preliminary specification

Audio processor for VHS hi-fi TDA9615H

3. Modes ‘loop-through’ and ‘record’ are equal in audio signal flow; FMOUT (pin 36) however is muted during
‘loop-through’ mode.
4. POR.

Table 7 Bit NTSC

NTSC(1) MODE DESCRIPTION

0 PAL hi-fi circuit in ‘PAL’ mode (FM carriers: 1.4 and 1.8 MHz)
1 NTSC(2) hi-fi circuit in ‘NTSC’ mode (FM carriers: 1.3 and 1.7 MHz)

Notes
1. Bit NTSC selects between the system standard settings for NTSC and PAL (SECAM) use. The auto-calibration
function uses the system standard HID frequency of 29.97 Hz for NTSC and 25 Hz for PAL. After calibration bit NTSC
allows immediate switching between the NTSC and PAL system standard.
2. POR.

Table 8 Bit MUTE

MUTE(1) MODE DESCRIPTION
0 − power mute function released; mute switches open
1 mute(2) power mute function activated; mute switches closed

Notes
1. Bit MUTE controls the line and RFC output mute switches at pins 13, 14 and 17 (power mute function). Power mute
is also automatically activated at supply voltage power-up or power-down (VCC; pin 35).
2. POR.

Table 9 Bits STBP and STBA

STBP STBA MODE DESCRIPTION

0 0 − (note 1) full operation
0 1(2) active standby(3) standby mode; reduced power consumption
1(4) X(5) passive standby(3) standby mode; minimum power consumption

Notes
1. POR.
2. By selecting STBA = 1 the TDA9615H is switched to low-power ‘active standby’ mode. To reduce power
consumption most circuits are switched off. RFC, line and decoder outputs however remain active. This way the
direct audio selections offered via the line output select and decoder output select functions (bits LOS and DOS of
the output byte) remain operable in this mode. The ‘Output Select’ mode signal is muted.
3. Calibration and I2C-bus registers are not affected by using ‘active standby’ or ‘passive standby’ mode.
4. By selecting STBP = 1 the TDA9615H is switched to minimum power ‘passive standby’ mode. All circuits except
power mute, I2C-bus and the line input reference buffer (voltage at pins 1 to 10 and 44) are switched off for minimum
power consumption. Use of the power mute function (bit MUTE of control byte) ensures pop-free switching of the line
and RFC output to and from ‘passive standby’ mode. To obtain minimum power consumption the power mute
function should be de-activated again during ‘passive standby’ mode.
5. X = don’t care.

Notes
1. Bits IS2, IS1 and IS0 select the input signal which is led to the volume controls of the hi-fi processing and generally
via the normal select function to the linear audio circuit (LINOUT; pin 20).
2. POR.
3. ‘Dub Mix’ is a special selection for linear audio use supporting audio dubbing (a video recorder feature mode for
sound recording of linear audio only). ‘Dub Mix’ connects the AUX input signal to the left channel
(1⁄2AUXL + 1⁄2AUXR) and the hi-fi output signal to the right channel (generally 1⁄2hi-fi left + 1⁄2hi-fi right but also
hi-fi left or hi-fi right can be selected). ‘Dub Mix’ also changes part of the ‘Output Select’ mode settings to ‘Normal’
mode for monitoring of the linear audio recording (see control bits OSN, OSR and OSL of the output byte for
‘Dub Mix’ mode input and output selection).

connection to an external linear audio circuit. The signal selected with the input select function (via
bits IS2, IS1 and IS0) is available in the following ways:
a) Left and right channel combined, optional including hi-fi volume control (1⁄2hi-fi left + 1⁄2hi-fi right).
b) Left channel only (language I), optional including left channel volume control.
Furthermore the SAP input (pin 44), tuner input (pins 1 and 2) or EXT2 input (pins 7 and 8) can be selected

1 1 1 Mix-Stereo mix of hi-fi stereo with normal (1⁄2hi-fi stereo + 1⁄2normal)

Notes
1. When no hi-fi signal is found on tape during ‘playback’ mode the auto-normal function is activated; all output select
function modes except ‘mute’ will be overruled and changed to ‘Normal’ mode. If muting of the hi-fi sound is desired
instead of selecting linear audio the normal input level (bits NIL3 to NIL0 of the select byte) should be set to mute.
Activation of the auto-normal function can be monitored by reading bit AUTN of the read byte.
2. If ‘Dub Mix’ mode is selected via the input select function (see control bits IS2, IS1 and IS0 of the input byte)
functionality of the modes ‘Mix-Left’, ‘Mix-Right’ and ‘Mix-Stereo’ are changed to support audio dubbing input mixing.
Hi-fi channel selection is offered for the input and normal sound is available at the output for monitoring of the linear
audio recording. See also Table 19.

Notes
1. Pin 39 (ENVOUT) or bit CALR of the read byte can be monitored to check for successful completion of the calibration.
It is advised to keep CALS logic 1 after calibration to ensure a reliable CALR state.
2. After a change of bit CALS from logic 0 to logic 1, an automatic frequency calibration is performed setting hi-fi
modem, band-pass filter and noise reduction. Use of auto-calibration is only needed after power-up of the supply
voltage (POR).

Notes
1. To maximize the output drive when using 12 V supply voltage (VCC; pin 35), the DC level of outputs LINEL, LINER,
DECL and DECR (pins 15, 16, 18 and 19) can be changed using bit VCCH.

PORR MODE DESCRIPTION
0 − (note 2) −
1 POR reset reset of POR signal bit

Notes
1. Bit POR of the read byte can be used to detect the occurrence of a power-on reset situation (bit POR reads logic 1
in case the I2C register contents equal the POR default state). When applying bit POR this way, PORR should be
used after a power-on reset to force a reset of the POR read bit state to logic 0.

Table 32 Bit CALR; notes 1 and 2

CALR DESCRIPTION
0 device is not calibrated
1 device has completed auto-calibration

Notes
1. Bit CALR = 0 indicates the device is not calibrated. After an automatic calibration is started by setting bit CALS of the
power byte the end of calibration is signalled by this bit. If for some reason a calibration cannot be completed (e.g.
no HID signal available or hi-fi processing is in ‘playback’ mode) CALR remains logic ‘0’. If calibration is lost due to
a power-on reset situation CALR will return to logic 0 as well.
2. Also the envelope output (pin 39) can be used to check for end of calibration.

Table 33 Bit AUTN; notes 1 and 2

AUTN DESCRIPTION
0 audio FM signal is detected at FM input
1 no audio FM signal detected; normal sound is selected instead of hi-fi

Notes
1. When hi-fi processing is in ‘playback’ mode but no hi-fi carrier input signal is detected the auto-normal function is
activated. Auto-normal overrules the ‘Output Select’ mode setting, selecting normal sound (i.e. linear audio) instead
of hi-fi. The state of this auto-normal function can be checked via bit AUTN.
2. The auto-normal function is only active (bit AUTN = logic 1) for hi-fi ‘playback’ mode (bit AFM = 0); during ‘record’ or
‘loop-through’ mode bit AUTN is always logic 0.

Table 34 Bit POR; notes 1 and 2

POR DESCRIPTION
0 I2C-bus bit state differs from power-on reset state
1 I2C-bus bit state equals power-on reset state

Notes
1. At power-on or during a power voltage dip, an internal power-on reset signal is generated which resets the I2C-bus
data bits to a predefined state. When the internal data bits are found to be in POR state (due to an actual power-on
reset but also if set via the I2C-bus) bit POR signals logic 1.
2. Using the POR bit to detect the occurrence of a power-on reset requires bit PORR to be set logic 1 after power-up.
Setting bit PORR forces the POR bit to logic 0 independent of other I2C-bus bit settings. After calibration is completed
also the CALR bit can be used to detect a power-on reset; calibration will be lost in such situation which is signalled
by CALR = 0.

Notes

2. Calibration may be lost when selecting product testing modes.
3. Audio output level for tests 25b and 25c (test output = line out) is typical −6.5 dBV (with input = −8 dBV or FM
deviation = 50 kHz; LOH = 0). Audio input level for tests 25a, 26a and 26c (test input = line in) is typical −6.5 dBV
(for output = −8 dBV or FM deviation = 50 kHz; hi-fi volume = −3 dB). The test outputs and test inputs used for
tests 25 and 26 directly connect to internal signal lines. Signals found here are not compensated for temperature or
tolerance spread, level measurements therefore can be used relative only. Absolute values are no indication of
overall performance.
