PBL 38582

Telephone Line interface circuit for

DECT, DAM, CT

Unisolated or Isolated

Description

Key Features

PBL 38582 is a monolithic bipolar integrated circuit for use as telephone line interface in

unisolated or isolated DECT and other cordless telephone residential base stations and

inanalog/digitalansweringmachinesorassecondlineinanunisolatedDECTtelephone

base station.

Transmit and receive gains are set by external components. On / Off switchable gain,

related to line, regulation for different current feeds can be set by external resistors.

Typical current feeds as 48 V, 2 • 200 ohm, 48 V 2 • 400 ohm and 60 V 2 • 600 ohm can

be handled. Application dependent parameters such as line balance, impedance to the

line and frequency response are set by external components. Parameters are set

•

Minimum number of inexpensive

external components, 5 capacitors

and 4 resistors.

Current range

5 - 130 mA(DIL),

5 - 100 mA(20-pin SO)

5 - 70 mA(16-pin SO) 385 82/2

Operation voltage range

down to 2 V.

•

independently which results in an easy adoption for various market needs.

Short start-up time.
