MSM7507-xx Overview
The MSM7507 is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz with filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, the device is optimized for ISDN terminals, digital wireless systems, and digital PBX systems. The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B.
