SC5313
4-CH STEREO AUDIO PROCESSOR
DESCRIPTION
The SC5313 is a digital controlled stereo audio processor with loudness
and tone, built-in volume, treble/bass tone, left/right balance and
loudness. Selectable input gain and external loudness function are
provided. Control is accomplished by serial bus microprocessor interface.
The AC signal settings is obtained by resistor networks and switches
combined with operational amplifiers.
FEATURES
* All functions programmable via serial Bus
* 4 independent speakers control, Independent mute function
* 3 stereo inputs
* Volume control in 1.25dB steps
* Treble and bass control
* Loudness function
APPLICATIONS
* Car audio
* CD
* Hi-Fi audio system

BUS INTERFACE PROTOCOL
1. The interface protocol comprises:
* A start conditions
* Address code,
* Data code (N-bytes + acknowledge)
* A stop condition
SC5313
2. A start condition is a HIGH to LOW transition of the DATA line while CLK is HIGH.
The stop condition is a LOW to HIGH transition of the DATA line while CLK is HIGH.
3. The microprocessor puts a resistive HIGH level on the DATA line during the acknowledge clock pulse.
The SC5313 that acknowledges has to pull-down the DATA line during the acknowledge clock pulse, so that
the DATA line is stable LOW during this clock pulse. The SC5313 which has been addressed has to generate an
acknowledge after the reception of each byte , otherwise the DATA line remain at the HIGH level during the ninth
clock pulse time. In this case the master transmitter can generate the STOP information in order to abort the
transfer.
