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 kW load, can directly drive a handset receiver
differentially.
