The World’s First Complete PLCC Packaged Modem

Description

Xecom’s XE2420 is the first complete modem available

in a PLCC package. This package is ideal for space

limited applications. The XE2420 is aimed at remote

monitoring applications in industrial, commercial and

residential locations.

Xecom offers two XE2420 models. The base XE2420

provides 2400 BPS data transfer for remote monitoring

applications. The XE2421 adds enhancements which

permit it to share a telephone line without interfering

with the telephone handset. Both models include user

transferrable FCC Part 68 Registration permitting direct

connection to the telephone line without further FCC

Part 68 testing.

The XE2420 and XE2421 use a standard PLCC

package with a unique lead-frame. This package design

is ideal for volume applications where automated

assembly can be efficiently utilized. It also provides the

world’s smallest embeddable modem package filling

less than one quarter of a cubic inch.
