µPD9903

µPD9903 ANALOG SUBSCRIBER LINE LSI (DIGITAL CODEC)

The µPD9903 is a digital CODEC that can be used in analog subscriber circuits such as private branch exchangers

(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.

Use of the µPD9903 in combination with a BS-SLIC (µPC7073) can reduce the number of components required

in analog subscriber circuits.

FEATURES

• Single-chip monolithic LSI (CMOS)

• PCM CODEC → oversampling-type A/D and D/A converters

• Programmable functions

• Termination impedance

• Hybrid balance network

• Feed resistance

• Feed current

• PAD control

• A-law and µ-law

• Digital gain set function

• Ring-Trip function

• Single power supply (+5 V)

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