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).
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.
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"
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.

I
Power-down mode control when powered down.
"L": Power-down mode
"H": Normal operation mode
During power-down mode, all input pins are disabled and output pins are
in the following states :
High impedance : SOUT, ROUT
"L": SYNCO, SCKO, MCKO
"H":
OF1
,
OF2
, X2
Holds the last state : WDT,
IRLD
Reset after the power-down mode is released.
