MSM7603 - Echo Canceler

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.

Features

  • Can handle both acoustic and telephone line echoes.
  • Switchable between m-law PCM and A-law PCM interfaces. (MSM7603B).
  • Cancelable echo delay time: MSM7603B-003 55 ms (max. ).
  • Echo attenuation : 30 dB (typ. ).
  • Clock frequency : 19.2 MHz 17.5 MHz to 20 MHz (when internal sync signal not used).
  • Power supply voltage : 2.7 V to 5.5 V.
  • Package: 28-pin plastic SSOP (SSOP28-P-485-0.65-K) (Product name : MSM7603-003GS-K) (Product name : MSM7.

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. www.DataSheet4U.com Echo is canceled, in digital signal processing, by estimating the echo path and generating a pseudo echo signal.
