SC14408 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 Analog Frontend is integrated. Direct connections towards microphone 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^TMCR16B 16 bit microcontroller takes care of all the higher protocol stack
