FUNCTIONAL DESCRIPTION
An overview of input/output selections is given in Figs 3 to 5.
Full control of the TDA9615H is accomplished via the 2-wire I2C-bus. Up to 400 kbits/s bus speed can be used, in
accordance with the I2C-bus fast-mode specification. The detailed functional description can be found in
Chapter “I2C-bus protocol”.

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 I
one data byte register is available without subaddressing.

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).
2
b) The status of hi-fi detection can be monitored via the I
C-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.

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.

Notes

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 I
2
C-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.
