TP3067AN
整体式串行接口联合PCM编解码器和过滤器 MONOLITHIC SERIAL INTERFACE COMBINED PCM CODEC AND FILTER
description
The TP3064A, TP3067A, TP13064A, and TP13067A are comprised of a single-chip PCM codec pulse-code-modulated encoder and decoder and PCM line filter. These devices provide all the functions required to interface a full-duplex 2-wire voice telephone circuit with a TDM time-division-multiplexed system.
Complete PCM Codec and Filtering Systems Include:
– Transmit High-Pass and Low-Pass Filtering
– Receive Low-Pass Filter With sin x/x Correction
– Active RC Noise Filters
– µ-Law or A-Law Compatible Coder and Decoder
– Internal Precision Voltage Reference
– Serial I/O Interface
– Internal Autozero Circuitry
µ-Law – TP3064B and TP13064B
A-Law – TP3067B and TP13067B
