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
●Reliable Silicon-Gate CMOS Technology
●Low Power Consumption:
● Operating Mode...80 mW Typical
● Power-Down Mode...5 mW Typical
●Excellent Power-Supply Rejection Ratio Over Frequency Range of 0 Hz to 50 kHz
●No External Components Needed for Sample, Hold, and Autozero Functions
●Precision Internal Voltage References
●Improved Version of TCM29C13 Series and TCM129C13 Series
