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 control, 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

V_DD: 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:

 Low power consumption

Operating mode:

64 to 2048 kbps

15 mW typ. (V_DD= 3.0 V)

Power-down mode:

3 W typ. (V_DD= 3.0 V)

 Master clock frequency:

 Analog output stage
