SC14428
Baseband Processor for FP & PP DECT and WDCT
1.0 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 connec-
tions towards PSTN or ISDN line interface are possible.
The SC14428 has a programmable Generic DSP opti-
mized 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.
