Abstract :
A single chip CPCM codec is described. This chip, which is fabricated in bipolar technology, meets all the D3 specifications. The circuit is capable of operating in a fully asynchronous transmit and receive mode, and provisions are made for zero code suppression and A/B signaling. Even with this signaling, the codec achieves a worst case idle channel noise of 13 dBrnC0.
