SC14402 Complete Baseband Processor for DECT Handsets PRELIMINARY February 1998 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 connections towards microphone and a (dynamical) loudspeaker 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.
