This version: Aug. 1998 MSM7602 Previous version: Nov. 1996
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 pact 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...
