ADPCM CODEC for digital cordless

telephones

PCD5032

FEATURES

APPLICATIONS

• G.721 compliant ADPCM encoding and decoding

• Digital Enhanced Cordless Telephony (DECT)

• CT2 cordless

• ‘Bitstream’ analog-to-digital and digital-to-analog

conversion

• Speech compression.

• On-chip receive and transmit filter

• On-chip ringer and tone generator

GENERAL DESCRIPTION

• Programmable gain of receive and transmit path

The PCD5032 is a CMOS device designed for use in

Digital Enhanced Cordless Telephone systems (DECT),

but also suitable for other cordless telephony applications

such as CT2. The PCD5032 performs analog-to-digital

and digital-to-analog conversion, ADPCM encoding and

decoding compliant to CCITT recommendation “G.721

(blue book, 1988)”. The PCD5032 contains on-chip

microphone and earpiece amplifiers. The device can be

used in both handset and base station designs.

• Serial ADPCM interface with independent timing for

maximum flexibility

• Linear PCM data accessible for digital echo cancelling

• Programmable via I²C-bus interface

• Fast receiver mute input via pin

• On-chip reference voltage

• On-chip symmetrical supply for electret microphone

• Few external components

• Low power consumption in standby mode

• Low supply voltage (single supply 2.7 V up to 5.5 V)

• CMOS technology

• Minimized EMC on digital outputs.
