SC14422

Complete Baseband Processor for DECT Base Stations

General Description

Preliminary document version 1.1.

The SC14422 is a 3.0 Volt CMOS IC optimized to handle

all the audio, signal and data processing needed within a

DECT basestation. An ADPCM transcoder, a very low

power CODEC and Analog Frontend are integrated. Di-

rect connections towards analog or ISDN line interface.

The SC14422 is designed to be compatible with many

radio interfaces. A dedicated TDMA controller handles all

physical layer slot formats and radio control.

The

CR16A processor core with external Program memory

(Flash or ROM) takes care of all the higher protocol stack.

Programmable I/O ports can be configured as chip selects

for I/O expanders, Serial Flash memory, interrupt source

or I/O. A digital serial interface can be configured to inter-

face to many codecs and ISDN devices with -Law, a-Law,

linear or transparent data formats.
