Overview

MV350S/350713507A MV3506 A-LAW CODEC WITH FILTER MV3507 jJ.-LAW CODEC WITH FILTER MV3507A jJ-LAW CODEC WITH FILTER AND AlB SIGNALLING The MV3506 and MV3507 are silicon gate CMOS Companding Encoder/Decoder integrated circuits designed to implement the per channel voice frequency Codecs used in PCM systems The chips contain the band-limiting filters and the analogue to digital conversion circuits that conform to the desired transfer characteristic.

The MV3506 provides the European A-Law companding and the MV3507 provides the North American Ii-Law companding characteristic.

These circuits provide the interface between the analogue signals of the subscriber loop and digital signals of the PCM highway in a digital telephone switching system.
