Digital TV Sound Processor (DTVSP)
TDA9875A

L
INE OUTPUT
The line output can provide an unprocessed copy of the
audio signal in the loudspeaker channels. This can be
either an external signal that comes from the dual audio
ADC, or a signal from an internal digital audio source that
comes from the dual audio DAC. The line output employs
amplifiers with two gain settings. The 3 dB position is
needed to compensate for the attenuation at the SCART
inputs, while the 0 dB position is needed, for example, for
non-attenuated external or internal digital signals
(see Section 6.3.4).

OUTPUTS
Signals from any audio source can be applied to the

digital crossbar switch and the DSP.
6.3.7
D
UAL AUDIO
DAC
The TDA9875A contains three dual audio DACs, one for
theconnectionfromtheDSPto theanalogcrossbarswitch
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 TDA9875A for the
connection of the analog crossbar switch section to the
DSP. The dual audio ADC consists of two bitstream
third-order sigma-delta audio ADCs and a high-order
decimation filter.
6.3.9
S
TANDBY MODE
The standby mode, selected by setting bit STDBY to
logic 1 (see Section 10.3.2) disables most functions and
reduces power dissipation. The analog crossbar switch
and the SCART section remain operational and can be
controlled by the I
2
C-bus to support copying of analog
signals from SCART-to-SCART.
Unused internal registers may lose their information in the
standby mode. Therefore, the device needs to be
initialized on returning to the normal operating mode. This
can be accomplished in the same way as after a Power-on
reset.

UPPLY GROUND
The different supply grounds V
SS
are internally connected
via the substrate. It is recommended to connect all ground
pins by means of a copper plane close to the pins.
