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 CompactRISCTM
CR16A 16 bit microcontroller with external ROM takes
care of all the higher protocol stack.
Features
s Integrated DECT Baseband transceiver optimized for
GAP handsets according to ETS 300 175-2, 175-3 &
175-8.
s 2.95 to 3.6 Volt operating voltage.
s Very low power in active and paging mode.
s Max 5V battery input.
s Embedded 16 bit CompactRISCTM Micro Controller.
(CR16A) with programmable clock speeds.
s ACCESSBUSTM or MICROWIRETM interfaces can be
handled.
s 4 kByte on-chip Data Memory.
s One full duplex ADPCM transcoder.
s On-chip 14-bit linear CODEC.
s 8 upto 38 dB gain differential microphone input buffer.
s 100 loudspeaker driver.
s Software controlled gain on audio input and output.
s On-chip gaussian Modulator.
s Peak hold ADC for RSSI measurement.
s Three general purpose inputs can be multiplexed on an
8 bit ADC with selectable ranges.
s Advanced battery management unit
s On board dedicated TDMA instruction co-processor
(DiP).
s Eight programmable control signals for radio front end.
s Serial interface to control radio front end circuitry.
s Full support of all data formats.
