MSM7736B-01 - Brand New Oki Semiconductor IC Chips
-
Description
The MSM7736B-01 is an IC chip developed for portable, handsfree communication. It features a built-in line echo canceler, acoustic echo canceler, and transmission signal noise canceler. The device includes a linear CODEC for the analog interface on both the acoustic-side and the line-side. It also offers gain and mute controls for data transmission and reception, as well as a m-law PCM/16-bit linear digital interface for memo recording and message output. With transfer clock and sync clock generators for digital communication, this IC chip is ideal for handsfree systems.
