MSM7602

Echo Canceler

GENERAL DESCRIPTION

The MSM7602 is an improved version of the MSM7520 with the same basic configuration. The

MSM7602 uses a 19.2 MHz clock frequency to meet PHS, the 3 V power supply (2.7 V to 5.5 V),

and compact packaging. Also, this device adds the howling detecter control pins and main clook

output pins. (See the Appendix)

The MSM7602 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 signal.

When used as an acoustic echo canceler, the device cancels the acoustic echo between the loud

speaker and the microphone which occurs during hands free communication such as with a

cellular phone or a conference system phone.

When used as a line echo canceler, the device cancels the line echo caused by impedance

mismatching in a hybrid.

In addition, the MSM7602 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, theMSM7602I/Ointerfacesupportsm-lawPCM. TheuseofasinglechipCODEC, such

as the MSM7566/7704 (3 V) or MSM7543/7533 (5 V), allows an economic and efficient echo

canceler configuration.
