SC14428 General Description
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.
The SC14428 has a programmable Generic DSP optimized for telecom applications.
The SC14428 is designed to fit to any radio interface. A dedicated TDMA controller handles all physical layer slot formats and radio control.
National Semiconductor's standard CompactRISCTM CR16C microprocessor takes care of all the higher protocol stack.
