TCM29C23 General Description

The TCM29C23 and TCM129C23 are single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM lines filters. These devices provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system. Primary applications include digital encryption systems, digital voice-band data storage systems, digital signal processing, and mobile telephones.

These devices are designed to perform the transmit encoding (A/D conversion) and receive decoding (D/A conversion) as well as the transmit and receive filtering functions in a pulse-code-modulated system. They are intended to be used at the analog termination of a PCM line or trunk.

The TCM29C23 and TCM129C23 provide the band-pass filtering of the analog signals prior to encoding and after decoding. These combination devices perform the encoding and decoding of voice and call progress tones as well as the signaling supervision information.

The TCM29C23 is characterized for operation from 0°C to 70°C. The TCM129C23 is characterized for operation from 40°C to 85°C.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values for maximum ratings are with respect to V_BB.
