Preliminary specification
Digital TV Sound Processor (DTVSP)
TDA9875

(M

OUTPUTS
Signals from any audio source can be applied to the
loudspeaker and to the headphone output channels via the
digital crossbar switch and the DSP.
6.3.7
D
UAL AUDIO
DAC
The TDA9875 contains three dual audio DACs, one for the
connection from the DSP to the analog crossbar switch
section and two for the loudspeaker and headphone
outputs. Each of the three dual low-noise high-dynamic
range DACs consists of two 15-bit DACs with current
outputs, followed by a buffer operational amplifier.
The audio DACs operate with four-fold oversampling and
noise shaping.
6.3.8
D
UAL AUDIO
ADC
There is one dual audio ADC in the TDA9875 for the
connection of the analog crossbar switch section to the
DSP. The dual audio ADC consists of two bitstream
3rd-order sigma-delta audio ADCs and a high-order
decimation filter.
6.3.9
S
TANDBY MODE
The standby mode (subaddress 1, bit 5) disables most
functions and reduces power dissipation. The analog
crossbar switch and the SCART section remains
operational and can be controlled by the I
2
C-bus to
support copying of analog signals from SCART 1 to
SCART 2 and vice versa.
Unused internal registers may lose their information in
standby mode. Therefore, the device needs to be
initialized on returning to normal operation. This can be
accomplished in the same way as after a power-on reset.
