TCM29C16N
联合单片PCM编解码器和过滤器 COMBINED SINGLE-CHIP PCM CODEC AND FILTER
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
● Replaces Use of TCM2910A in Tandem With TCM2912C
● 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
● Direct Replacement for Intel 2913, 2914, 2916, and 2917
● Recommended for Direct Voice Applications
