description

The TCM29C13, TCM29C14, TCM29C16,

TCM29C17, TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters. They provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system, and are intended to replace the TCM2910A in tandem with the TCM2912C. Primary applications include:

Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone systems
Subscriber line concentrators
Digital-encryption systems
Digital voice-band data-storage systems
Digital signal processing

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 TCM129C13, TCM129C14, TCM129C16, TCM129C17, TCM29C13, TCM29C14, TCM29C16, and TCM29C17 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 and supervision information.

The TCM29C13, TCM29C14, TCM29C16, and TCM29C17 are characterized for operation from 0°C to 70°C. The TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are characterized for operation from -40°C to 85°C.
