Overview
E2U0064-18-82 ¡ Semiconductor MSM7603/7603B ¡ Semiconductor Echo Canceler This version: Aug.
1998 MSM7603/7603B GENERAL DESCRIPTION The MSM7603/7603B is an improved version of the MSM7602 with basically the same configuration, and offers twice the cancelable echo delay time of the MSM7602.
The MSM7603B I/O interface allows switching between m-law PCM and A-law PCM.
The MSM7603/7603B is a low-power CMOS IC device for canceling echo (in an acoustic system or telephone line) generated in a speech path.

com Echo is canceled, in digital signal processing, by estimating the echo path and generating a pseudo echo signal.
When used as an acoustic echo canceler, the device can cancel the acoustic echo, between the loud speaker and the microphone, which occur during hands free communication such as on a cellular phone or a conference system phone.
When used as a line echo canceler, the device can cancel the line echo which returns due to impedance mismatching in a hybrid.
