Description

Sync signal for transmit/receive serial data.

This pin uses the external SYNC or SYNCO.

Input the PCM CODEC transmit/receive sync signal (8 kHz).

—

SYNC

SOUT

ROUT

PD0

Transmit serial data.

Outputs the PCM signal synchronized to SYNC and SCK.

This pin is in a high impedance state during no data output.

Receive serial data.

Outputs the PCM signal synchronized to SYNC and SCK.

This pin is in a high impedance state during no data output.

I/O

This is the bidirectional bus pin for parallel data transfer between the

master chip and slave chip when used in a cascade connection.

The PD15 pin corresponds to MSB.

This pin is in a high impedance state during no data

output. Data is loaded in at the falling edge of SFx.

Controls the howling detect function. This pin detets and cancels a howling

generated during hand-free talking for acoustic system.

This function is used to cancel acoustic echoes.

• Single Chip or Master Chip in a Cascade Connection

"L": Howling detector ON

"H": Howling detector OFF

• Slave Chip in a Cascade Connection

Fixed at "L"

X1/CLKIN

External input for the basic clock (17.5 to 20 MHz) or for the crystal

oscillator.

When the internal sync signal (SYNCO, SCKO) is used, input the basic

clock of 19.2 MHz.

Crystal oscillator output.

Used to configure the oscilation circuit.

Refer to the internal clock generator circuit example.

When inputting the basic clock externally, insert a 5 pF capacitor with

excellent high frequency characteristics between X2 and GND.
