MSM7602 Echo Canceler

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 cancel.
