PRELIMINARY  
February 1998  
SC14402  
Complete Baseband Processor for DECT Handsets  
General Description  
Preliminary document version 1.5.  
■ 2.95 to 3.6 Volt operating voltage.  
■ Very low power in active and paging mode.  
■ Max 5V battery input.  
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.  
■ Embedded 16 bit CompactRISCTM Micro Controller.  
(CR16A) with programmable clock speeds.  
■ ACCESSBUSTM or MICROWIRETM interfaces can be  
handled.  
■ 4 kByte on-chip Data Memory.  
■ One full duplex ADPCM transcoder.  
■ On-chip 14-bit linear CODEC.  
■ 8 upto 38 dB gain differential microphone input buffer.  
■ 100 W loudspeaker driver.  
■ Software controlled gain on audio input and output.  
■ On-chip gaussian Modulator.  
■ Peak hold ADC for RSSI measurement.  
■ Three general purpose inputs can be multiplexed on an  
8 bit ADC with selectable ranges.  
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.  
TM  
National Semiconductors standard CompactRISC  
CR16A 16 bit microcontroller with external ROM takes  
care of all the higher protocol stack.  
■ Advanced battery management unit  
■ On board dedicated TDMA instruction co-processor  
(DiP).  
Features  
■ Integrated DECT Baseband transceiver optimized for  
GAP handsets according to ETS 300 175-2, 175-3 &  
175-8.  
■ Eight programmable control signals for radio front end.  
■ Serial interface to control radio front end circuitry.  
■ Full support of all data formats.
