DATA SHEET
MOS INTEGRATED CIRCUIT
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.)
