ML7021
Echo Canceler
FEDL7021-03
Issue Date: Jun. 1, 2005
GENERAL DESCRIPTION
The ML7021 is an improved version of the MSM7602 with the reduced cancelable echo delay
time and additional 2100Hz tone detection function.
The ML7021 is a low-power CMOS 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 signal.
The ML7021 makes possible a quality conversation by controlling the noise level and preventing
howling with howling detector, double talk detector, attenuation function, and a gain control
function. The devise also controls the low level noise with a center clipping function.
Further, the ML7021 I/O interface supports
m-law
PCM . The use of a single chip CODEC, such
as the MSM7566/7704 (3 V) or MSM7543/7533 (5 V), allows a simplified and efficient echo
canceler configuration.
