Digital TV Sound Processor (DTVSP)
TDA9875A
10.3.38 B
EEPER FREQUENCY CONTROL REGISTER
This register is used to select from sample beeper oscillator frequencies. The beeper output signal is added to the Main
and Auxiliary channel output DAC.
Due to the frequency response of the audio DACs upsampling filters, the 25 kHz beep is approximately 5 dB louder than
the 390 Hz beep.
Table 81
Subaddress 43 (note 1)
Note
1.
The default setting at power-up is 0000 0000.
10.3.39 B
EEPER VOLUME CONTROL REGISTER
This register is used to set the beeper volume. The gain setting is relative to digital full-scale at the input to the Main and
Auxiliary channel output DACs. The beeper volume is independent of any other volume setting.
The beeper signal is added to the Main and Auxiliary channel output signals in the 2
×
f
s
domain. The beeper volume
should be set with great care, when the audio signals in the Main and Auxiliary channels are close to digital full-scale, to
avoid output signal distortion due to overload.
