GENERAL DESCRIPTION
The MSM7543 and MSM7544 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 digital wireless systems, ISDN terminals, and digital PBXs. The MSM7543 and MSM7544 use newly- designed operational amplifiers to keep small current deviations caused by power voltage fluctuations.
The devices use the same transmission clocks as those used in the MSM7508B and MSM7509B.
The analog output signal, which is of a differential type and can drive a 600 W load, can directly drive a handset receiverFEATURES
• Single power supply: +5 V ±5%
• Low power consumption
Operating mode: 20 mW Typ. 31.5 mW Max. VDD = 5 V
Power save mode: 4.5 mW Typ. 8 mW Max. VDD = 5 V
Power down mode: 1.5 mW Typ. 3 mW Max. VDD = 5 V
• ITU-T Companding law
MSM7543: m-law
MSM7544: A-law
• The transmission characteristics of the devices comply with ITU-T G.714
