Additional preview pages of the MSM7602 datasheet.

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.

Handles both acoustic echoes and telephone line echoes.
Cancelable echo delay time: MSM7602-001 For a single chip: 23 ms (max. ) MSM7602-011 For a cascade connection (can also be used for a single chip) Master chip: 23 ms (max. ) Slave chip: 31 ms (max. ) Cancelable up to 209 ms (1 master plus 6 slaves) For a single chip: 23 ms (max. ).
Echo attenuation : 30 dB (typ. ).
Clock frequency : 19.2 MHz External input and internal oscillator circuit are provided.
