(PBXs) and switching equipment for central offices. It features three of the functions required for analog subscriber

circuits: 2W/4W conversion, CODEC supervision, and subscriber line supervision.

in analog subscriber circuits.

FEATURES

•

• Digital gain set function

• Ring-Trip function

• Single power supply (+5 V)

• Low power consumption during standby mode: 20 mW (TYP.)

ORDERING INFORMATION

The PD9903 is a digital CODEC that can be used in analog subscriber circuits such as private branch exchangers

Use of the PD9903 in combination with a BS-SLIC ( PC7073) can reduce the number of components required

Single-chip monolithic LSI (CMOS)

PCM CODEC

Programmable functions

• Termination impedance

• Hybrid balance network

• Feed resistance

• Feed current

• PAD control

• A-law and -law
