Multi-Standard CMOS Single Chip

Telephone IC with Dual Soft Clipping

Austria Mikro Systeme International AG

General Description

The AS253x is a CMOS integrated circuit that contains

all the functions needed to form a high performance

electronic telephone.

Key Features

❑ Line/speech circuit, LD/MF repertory dialler and

tone ringer on one 28 pin CMOS chip

❑ Operating range from 13 to 100 mA (down to 5 mA

with reduced performance)

❑ Soft clipping to avoid harsh distortion

❑ Volume control of receive signal

❑ Line loss compensation selectable by pin option

❑ Low noise (max. - 72 dBmp)

❑ Real or complex impedance

❑ NET 4 compatible

❑ LD/MF switchable dialling

❑ Pacifier tone during programming

❑ 31 digit last number redial

❑ Repertory memories (not AS2534), 4 direct/10

indirect (AS2533/6), 12 direct (AS2535)

❑ Repeat dialling by busy or engaged (not AS2535)

❑ Sliding cursor protocol with comparison

❑ Pause key for access pause or wait function

❑ 3 flash keys, 100 ms, 280 ms and 375/600 ms

❑ On chip MF filter (CEPT CS 203 compatible)

❑ Ring frequency discrimination

ThedeviceincorporatesLD/MFrepertorydialling,melody

generation, ring frequency discrimination and a high

quality line/speech circuit.

A RAM is on chip for a 31 digit last number redial and

memories (not AS2534) each containing up to 21 digits/

data. The sliding cursor procedure makes the LNR

function easy to use under various PABX systems. Also

centrex keys (not AS2535) are provided.

Thedeviceincorporateavolumecontrolfortheearpiece.

The volume can be controlled by the VOL key (+ 5.4 dB)

or by the –/+ keys (+8.1 dB/-5.4 dB in 5 steps).

The versatility of the circuit is provided by pin options

and a few external components. This allows easy

adaptation to different PTT requirements.

❑ 3-tone melody generator

Package

Available in 28 pin SOIC or DIP.
