SC14402
Complete Baseband Processor for DECT Handsets
General Description
Preliminary document version 1.5.
The SC14402 is a 3.0 Volt CMOS chip optimized to handle
all the audio, signal and data processing needed within a
DECT handset. An ADPCM transcoder, a very low power
CODEC and Analog Frontend is integrated. Direct con-
nections towards microphone and a (dynamical) loud-
speaker are provided.
The SC14402 is designed such that it is compatible with
many radio interfaces.
A dedicated TDMA controller handles all physical layer
slot formats and radio control.
National Semiconductors standard CompactRISC
CR16A 16 bit microcontroller with external ROM takes
care of all the higher protocol stack.
