MSM7717-01
Single Rail CODEC
FEDL7717-01-01
Issue Date: Jun. 21, 2012
GENERAL DESCRIPTION
The MSM7717 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 and telephone terminals in digital wireless systems.
The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B.
The analog output, which can drive a 1.2 kΩ load, can directly drive a handset receiver differentially.
