联合单片PCM编解码器和过滤器 COMBINED SINGLE-CHIP PCM CODEC AND FILTER

description

The TCM29C13A, TCM29C14A, TCM29C16A, TCM29C17A, TCM129C13A, TCM129C14A, TCM129C16A, and TCM129C17A are single-chip PCM codecs pulse-code-modulated encoders and decoders and PCM line filters. These devices provide all the functions required to interface a full-duplex 4-wire voice telephone circuit with a time-division-multiplexed TDM system. These devices are intended to replace the TCM2910A or TCM2911A 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

Replace Use of TCM2910A and TCM2911A in Tandem With TCM2912B/C
