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 com telephone line) generated in a speech path.
Echo is canceled (in digital signal processing) by estimating the echo path and generating a pseudo-echo sign...
