IDT821034DN Datasheet PDF - Integrated Device Technology

●DESCRIPTION:

●The IDT821034 is a single-chip, four channel PCM CODECwith onchip filters and programmable gain setting. This device provides both m-Law and A-Law companding digital-to-analog and analog-to-digital conversions based on ITU-T G.711 - G.714 specifications. The digital filters in IDT821034 provides the necessary transmit and receive filtering for voice telephone circuit to interface with time-division multiplexed systems.
