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 CompactRISCTM CR16B 16 bit microcontroller takes care of all the higher protocol stack.
