TCM129C13N

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
