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

? 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
