Description

Control for the ATT function.

ATT

This pin prevents howling by attenuators (ATT) for the RIN input and SOUT

output.

If there is input only to RIN, the ATT for the SOUT output is activated.

If there is no input to SIN, or if there is input to both SIN and RIN, the ATT

for the RIN input is activated.

Either the ATT for the RIN output or the ATT for the SOUT is always

activated in all cases, and the attenuation of ATT is 6 dB.

• Single Chip or Master Chip in a Cascade Connection

"H": ATT OFF

"L": ATT ON

"L" is recommended if performing echo cancellation.

• Slave Chip in a Cascade Connection

Fixed at "L"

This input signal is loaded in synchronization with the falling edge of the

INT signal or the rising edge of the RST signal.

INT

Interrupt signal which starts 1 cycle (8 kHz) of the signal processing.

Signal processing starts when "H"-to-"L" transition is detected.

• Single Chip or Master Chip in a Cascade Connection

Connect the IRLD pin.

• Slave Chip in a Cascade Connection

Connect the IRLD pin of the master chip.

INT input is invalid for 100 ms after reset due to initialization.

Refer to the control pin connection example.

IRLD

Load detection signal output when the SIN and RIN serial input data is

loaded in the internal registers.

• Single Chip

Connect to the INT pin.

• Master Chip in a Cascade Connection

Connect to the INT pin of the master chip and all the slave chips.

• Slave Chip in a Cascade Connection Leave open.

Refer to the control pin connection example.

Transmit serial data.

SIN

RIN

SCK

Input the PCM signal synchronized to SYNC and SCK. Data is read in at

the falling edge of SCK.

Receive serial data.

Input the PCM signal synchronized to SYNC and SCK. Data is read at the

falling edge of SCK.

Clock input for transmit/receive serial data.

This pin uses the external SCK or the SCKO.

Input the PCM CODEC transmit/receive clock (64 to 2048 kHz).
