MSM7578V

MSM7578V Single Rail CODEC FEDL7578V-01 Issue Date: Jun. 21, 2012 GENERAL DESCRIPTION The MSM7578V is 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 particularly optimized for telephone terminals in digital wireless systems and ISDN systems. The devices use the same transmission clocks as those used in the MSM7508B and MSM7509B. The analog output signal can directly drive a piezoelectric type handset receiver. FEATURES Single power supply: +5.0 V 5% Low power consumption Operating mode: 25 mW Typ. 47 mW Max. VDD = 5 V Power down mode: 0.05 mW Typ. 0.3 mW Max. VDD = 5 V ITU-T Companding law MSM7578V: μ/A-law pin-selectable Built-in PLL eliminates a master clock Serial data rate: 64/128/256/512/1024/2048 kHz 96/192/384/768/1536/1544/200 kHz Adjustable transmit gain ...
