This version: Aug. 1998 MSM7620 Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM7620 is an improved version of the MSM7520 with the same basic configuration. The MSM7620 includes following improvements: a modified through mode, timing control of the control pin input, and a thinner package. The MSM7620 also provides a pin-for-pin replacement with the MSM7520. The MSM7620 is a low-power CMOS IC device for canceling echo (in an acoustic system or .. telephone line) generated in a speech path. Echo is canceled (in digital signal processing) by estimating the echo path and generating a pseudo-echo...
