E2U0041-28-81 ¡ Semiconductor MSM7717-01/02/03 ¡ Semiconductor Single Rail CODEC This version: Aug. 1998 MSM7717-01/02/03 Previous version: Nov. 1996 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. FEATURES • Single power supply: 2.7 V to 3.8 V • Low power consumption Operating mode: 20 mW Typ. VDD = 3 V Power-down mode: 0.
