Preliminary specification
Digital TV sound demodulator/decoder
TDA9874A
Notes
1.
Definition of levels and level setting:
a) The full-scale level for analog audio signals is V
FS
= 1.4 V (RMS). The nominal level at the digital crossbar switch
is defined at
15 dB (FS).
b) Nominal audio input levels: external, mono: 500 mV;
9 dB (FS).
Audio performance is limited by the dynamic range of the NICAM 728 system. Due to companding, the quantization
noise is never lower than
62 dB with respect to the input level.
FM source; in dual mode only A (respectively B) signal modulated; measured at B (respectively A) channel output;
V
o
= 1 V (RMS) of modulated channel.
FM source; in stereo mode only L (respectively R) signal modulated; measured at R (respectively L) channel output;
V
o
= 1 V (RMS) of modulated channel.
If the supply voltage for the TDA9874A is switched off, because of the ESD protection circuitry, all audio input pins
are short-circuited.
The Philips crystal (order number 9922 520 20106) is suitable for this application.
