PIN AND FUNCTIONAL DESCRIPTIONS

GND

Ground, 0 V.

SIP1, SOP1

PCM serial data input (SIP1) and output (SOP1) for Channel 1.

SOP1 is an open-drain output, which goes into a high impedance state after a continuous 8-bit

serial data output.

SIP2, SOP2

PCM serial data input (SIP2) and output (SOP2) for Channel 2.

SOP2 is an open-drain output, which goes into a high impedance state after a continuous 8-bit

serial data output.

SIP3, SOP3

PCM serial data input (SIP3) and output (SOP3) for Channel 3.

SOP3 is an open-drain output, which goes into a high impedance state after a continuous 8-bit

serial data output.

SIP4, SOP4

PCM serial data input (SIP4) and output (SOP4) Channel 4.

SOP4 is an open-drain output, which goes into a high impedance state after a continuous 8-bit

serial data output.

PAD10 - PAD40, PAD11 - PAD41

PAD mode control.

The PCM output can be attenuated by 12 dB or 6 dB and set to an out-of-service pattern (idle

pattern) by controlling these pins. Set these pins to digital "0" level during normal operation.The

control sequences are as follows:

PAD11 - PAD41

PAD10 - PAD40
