MSM7731-01 Datasheet Multifunction PCM CODEC (Voice Signal Processor)

Manufacturer: OKI Electric

Overview: E2U0060-18-84 ¡ Semiconductor MSM7731-01 ¡ Semiconductor Multifunction PCM CODEC (Voice Signal Processor) This version: Aug.

General Description

The MSM7731 is an LSI device developed for portable, handsfree communication with built-in line echo canceler, acoustic echo canceler, and transmission signal noise canceler.

Built-in to the voice signal interface is a linear CODEC for the analog interface on the acoustic-side, and a linear CODEC for the analog interface on the line-side.

On the line-side, in addition to the analog interface, there is also a m-law PCM/16-bit linear digital interface.

Key Features

  • Single 3 V power supply operation (2.7 V to 3.6 V).
  • Built-in 2-channel (line and acoustic) echo canceler Echo attenuation : 35 dB (typ. ) Cancelable echo delay time : Line echo canceler + acoustic echo canceler : Tlined = 27 ms (max. ), Tacoud = 59 ms.
  • Tlined (max. ) Acoustic echo canceler only : Tacoud = 59 ms (max. ).
  • Built-in transmission signal noise canceler Noise attenuation: 13 dB (typ. ) for white noise 40 dB (typ. ) for single tone.
  • Built-in 2-cha.
