The fader is located at the end of the tone/volume chain. The balance between the front
and rear channel can be controlled by attenuation of either the front or the rear channel.
Control range is 0 dB to 64 dB with a step size of 1 dB. Optionally the fader attenuation
can be activated for front and rear channels together.
The tone control output signal is available on two pins. Furthermore two input pins allow
connection to the fader block for front and rear line outputs, or alternatively for rear output
only. This allows connection of an external sound processing circuit for equalizing,
surround sound or sound stage positioning. Also input or mixing of an external signal
source like navigation voice or beep can be realized.
The RDS demodulator recovers and regenerates the continuously transmitted RDS or
RBDS data stream that may be part of the FM MPX signal and provides the signals clock
(RDCL) and data (RDDA) for further processing by a hardware or software RDS decoder.
Unbuffered demodulator output and buffered 16-bit output mode are available. The output
modes are compatible with stand-alone demodulator devices as well as digital and analog
signal processor standards. In case of buffered output mode additional RDS Quality
(RDQ) demodulation quality information is available optional.
SDA and SCL HIGH and LOW internal thresholds are specified according to both 2.5 V
and 3.3 V I
