Cordless telephone, answering

machine line interface

Key Features

Analogue line interface and speech circuit

for a/b terminals on a 28-pin CMOS-IC

2 balanced transmit inputs

3 unbalanced transmit inputs

2 buffered single ended receive outputs

(RL>150

Ω)

1 auxiliary single ended receive output

(RL>10k

Ω)

Low noise (max. -72dBmp)

Soft clipping to avoid harsh distortion

Operating range from 15mA to 100mA

(down to 5mA with reduced performance)

Line loss compensation selectable by pin

option

Real and complex impedance selectable by

external components

Side tone adaptation selectable by external

components

Digital controls input for mode selection

Rx volume control

General Description

AS2504 is a CMOS integrated circuit that

incorporates DC and AC line adaptation (DC-

mask

and

synthesised

AC-impedance

of

1000

Ω) as well as a speech circuit with

softclipping, line loss compensation and Rx-

volume control. It shall act as an a/b-line

powered or auxiliarily powered device, which is

controlled by a CPU.

Application

Cordless base stations, answering machines,

a/b-line or auxiliary powered telephone sets.

Package

Available in 28 pin SOIC
