DESCRIPTION
X Channel Data In. Sampled on the falling edge of CLKP during
selected time slots with MSB first.
X Channel Data Out. Updated on the rising edge of CLKP during
selected time slots with MSB first.
Y Channel Data In. Sampled on the falling edge of CLKA during
selected time slots with MSB first.
Y Channel Frame Sync. Master Y Channel Frame Sync. Signal
followed by the first time slot of transmission. It can be either
input or output by initial setup sequence.
Y Channel Data Out. Updated on the rising edge of CLKA
during selected time slots with MSB first.
Reset. Low active signal to force chip reset.
Crystal In & Out. 14.318 MHz Crystal connected∗∗∗.
PCM Clock. It can be either input created by external control
circuit, or output generated by internal control circuit.
ADPCM Clock. It can be either input created by external control
circuit, or output generated by internal control circuit.
Sync 1. Frame sync. for 1st CODEC.
Sync 2. Frame sync. for 2nd CODEC.
Sync 3. Frame sync. for 3rd CODEC.
Sync 4. Frame sync. for 4th CODEC.
TM1 &TM0 . Tie to Ground for normal operation.
A1 & A0. Address ID key for 3-wire serial port. If match, 3-wire
serial port can be enabled for configuration.
Serial Data In. Data for configuration on the fly by 3-wire serial
port. Sampled on the rising edge of SCLK with LSB first.
Serial Data Out. Output data after sending Read Memory
command by 3-wire serial port. Sampled on the rising edge of
SCLK with LSB first.
Serial Clock. Used to write to the 3-wire serial port registers or
output data from 3-wire serial port registers.
Serial Port Chip Select. Low active to enable 3-wire serial port.
Power. 3.3 Volts.
Ground. 0 Volt.
∗∗∗For clock source other than 14.318MHz, please contact Atelic Systems.
