SC14422

Complete Baseband Processor for DECT Base Stations

General Description

■ 2k + 4kbyte Data Memory.

Preliminary document version 1.1.

■ Two full duplex 32 kbits/sec ADPCM transcoder.

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.

■ 14-bit linear CODEC with programmable gain

■ Serial interface to external codecs and ISDN interface

circuits.

■ Echo canceller, two echo suppressors, DTMF genera-

tor, sidetone and artificial echo loss.

■ On-chip gaussian Modulator.

The SC14422 is designed to be compatible with many

radio interfaces. A dedicated TDMA controller handles all

physical layer slot formats and radio control.

■ Peak hold ADC for RSSI measurement

■ Three input 8 bit successive approximation ADC.

■ On board programmable Dedicated Instruction Proces-

sor (DIP) for all TDMA based events.

■ Protected and unprotected half, full and double slot B-

fields D00, D08, D32 and D80

■ Standard DECT encryption with different keys for

different MAC-connections.

■ 6 MAC connections can be handled simultaneously.

■ Flexible three wire interface to radio front synthesizer.

■ Three general purpose I/O ports with programmable in-

terrupts.

The integrated National Semiconductor’s standard

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 m-Law, a-Law,

linear or transparent data formats.

■ General purpose full duplex UART.

Features

■ SPI^TMand MICROWIRE^TMinterfaces.

■ Two general purpose timers and watchdog timer.

■ Programmable chip selects to 8 bit wide ROM, SRAM

NAND Flash Memory and I/O expanders.

■ Capture timer for frequency measurement for e.g. me-

tering, ringing and call progress tone detection.

■ 100 pin TQFP-100 package.

■ Integrated DECT base band transceiver optimized for

GAP base stations according to ETS 300 175-2, 175-3

& 175-8.

■ 3.0 to 5.5 Volt operating voltage.

■ Embedded 16 bit CompactRISC^TMCR16A Microproc-

essor with In System Emulation (ISE) mode.
