Single Rail CODEC

GENERAL DESCRIPTION

The MSM7508B and MSM7509B are single-channel CODEC CMOS ICs for voice signals ranging

from 300 to 3400 Hz. These devices contain filters for A/D and D/A conversion.

Designed especially for a single-power supply and low-power applications, these devices are

optimized for telephone terminals in ISDN and digital wireless systems.

The MSM7508B/MSM7509B are the transmission-clocks extended versions of the MSM7508/

MSM7509. It is recommended to use the MSM7508/MSM7509 for the transmission clocks of 64,

128, 256kHz.
