Overview
FEDL7041-05 Issue Date: Dec.
3, 2007 ML7041 Audio CODEC GENERAL DESCRIPTION The ML7041 is a single-channel full duplex CODEC LSI device which performs mutual transcoding between the analog voice band signals ranging from 300 to 3400 Hz and the 64 kbps PCM serial data.
Provided with such functions as DTMF Tone generation, transmit/receive data gain c ontrol, side-tone path, and low-dropout regulator, the ML7041 is best suited for telephone terminals in digital wireless systems.
FEATURES  Single 3 V power supply VDD: 2.
4 to 3.
3 V  Coding format: PCM -law/PCM A-law/14-bit linear mode selectable  PCM interface timing: Long frame synchronous timing/short frame synchronous timing selectable  Transmit/receive full-duplex operation  Serial PCM transmission data rate: 64 to 2048 kbps  Lo w power consumption Operating mode: 15 mW typ.
