56 KBPS DAA in a PLCC Package

Description

Features

Xecom’s XEV90 is a complete DAA integrated into a

compact PLCC package. The XEV90 supports analog

data transfer to 56 KBPS. The 68-Pin PLCC package

permits automated, high-volume assembly.

* Package: 68-Pin PLCC (only 18 pins used)

dimensions 0.952 inches by 0.952 inches by 0.170

inches high

* Meets Total Harmonic Distortion requirements for

reliable 56 Kbps modems (-85 dB typical);

The XEV90 does not sacrifice performance for small size

and surface-mount convenience. The heart of the XEV90

is a proprietary, low profile, low distortion transformer.

This wide bandwidth, low distortion device provides the

clear signal path required for 56 KBPS analog data

transfer.

* Integrated Low-Distortion Telephone Line

Transformer

* Integrated Ring Detection with active high and

active low ouput signals

* Operates on either a single Power Supply of +5 or

+ 3 Volts;

* Solid-State Hookswitch Control with active high

and active low inputs;

Like all Xecom DAA's the XEV90 is a complete

telephone line interface. It includes the telephone line

transformer, line current holding circuit, hookswitch and

ring indicator. The XEV90 replaces the dozens of

components found in a discrete DAA design.

* FCC Part 68 Compliant;

* Extended Temperature Range available;
