FULLY FEATURED PSTN INTERFACE

FEATURES

‹

A highly featured PSTN Interface

(COIC, FXO, DAA, Trunk Interface) in a

single DIL or 12mm high SIL device.

+5V or +3.3V supply.

Transformer isolation providing high

common-mode rejection (CMRR) for

use in un-grounded systems.

‹

Highly integrated with on-board loop

switch and diode bridge.

Loop start circuit, ringing detect and

loop current detection. Parallel phone

detect.

‹

Tip-ring polarity detect (for Caller Line

ID and remote metering) and on-hook

reception.

• Approved to:

EN 60950-1:2001

‹

Meets requirements of FCC Pt68.

Low cost power cross protection.

Programmable d.c. mask, line and

network impedances, allows use in any

market.

DESCRIPTION

The Ag2120 is a self-contained highly integrated PSTN Interface Circuit in a single SIL or DIL

module, which complies with RoHS requirements.

In addition to the features listed, the Ag2120 allows flexible programming of many functions,

including the dc voltage mask and impedances. The Ag2120 meets international safety and

regulatory requirements.

The device requires a minimum of external components and has been specified for ease of use,

to allow reduced time to market.

The Ag2120 is designed for all applications, including those where there is a high level of

common mode interference, such as PABX, long loop applications and systems without a

ground connection.
