MSM7603, Echo Canceler

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 ec
