SC14408
Complete Baseband Processor for DECT Handsets
General Description
The SC14408 is a CMOS chip optimized to handle all the
audio, signal and data processing needed within a DECT
(1.9GHz) or in the 2.4GHz ISM digital band handset. An
ADPCM transcoder, a very low power CODEC and Ana-
log Frontend is integrated. Direct connections towards mi-
crophone and a (dynamical) loudspeaker are provided.
Duplex quality handsfree operation is integrated.
The SC14408 is designed to fit to any radio design.
A dedicated TDMA controller handles all physical layer
slot formats and radio control.
National Semiconductors standard CompactRISC
TM
CR16B 16 bit microcontroller takes care of all the higher
protocol stack.
