SC14408 - Complete Baseband Processor for DECT Handsets

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.

Key Features

  • I Integrated DECT Baseband transceiver optimized for GAP handsets according to ETS 300 175-2, 175-3 & 175-8. I Two on board low drop voltage regulators with 2.5V and 3.0- 3.8V (with external resistors the voltage can be determined) output. I 2V upto 3.6V battery input with onboard step up converter. I Advanced battery management unit I Very low power in active and paging mode. ________________________________________________________________________________________________ System Diagram © 200.
