Product Summary

The IDT821034DN is a single-chip four channel PCM CODEC with on-chip 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 the IDT821034DN provide the necessary transmit and receive filtering for voice telephone circuit to interface with time-division multiplexed systems. The IDT821034DN has a flexible PCM interface with software selectable timing modes and independently programmable time slot for each transmit and receive channel. It also integrates the SLIC signaling functions through internal registers. The CODEC and SLIC control/status registers are accessed via the Serial Control Interface. The IDT821034DN can be used in digital telecommunication applications such as PBX, Central Office Switch, Digital Telephone and Integrated Voice/Data Access Unit.
