GENERAL DESCRIPTION
   The ML7037-003 is an IC 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 PCM CODEC for the analog interface on the acoustic-side, and another PCM CODEC for the analog interface on the line-side. On the line-side, in addition to the analog interface, there is also a -law PCM/16-bit linear digital interface.

   Equipped with gain and mute controls for data transmission and reception, a -law PCM/16-bit linear digital interface for memo recording and message output, and transfer clock and sync clock generators for digital communication, this device is ideally suited for a handsfree system.
