SC14428 Overview
.The SC14428 is a CMOS IC optimized to handle all the audio, signal and data processing needed within a DECT (1.9 GHz) or 2.4GHz ISM digital band base stations and handsets. A four channel ADPCM transcoder, a very low power 16 bit Codec and Analog Frontend are integrated. Direct connections towards PSTN or ISDN line interface are possible.
