MSM7570L-01/02  
Multi-Function ADPCM CODEC  
GENERAL DESCRIPTION  
The MSM7570L-01/02, developed for advanced digital cordless telephone systems, are single  
channelADPCMCODECICswhichperformmutualtranscodingbetweentheanalogvoiceband  
signal and 32 kbps ADPCM serial data.  
The devices include DTMF Tone and several types of tone generation, transmit/receive data  
mute and gain control, side-tone path and gain control, and VOX function.  
Using advanced circuit technology, these devices operate from a single 3 V power supply and  
provide low power consumption.  
Note: The MSM7570L–01differs from MSM7570L–02 in Ringing Tone Frequency.
