Compact 1200 bps Modem
Description
The XE1276A is the successor to the XE1276.
Several improvements have been incorporated in
the XE1276A. Power consumption has been
reduced, an automatic Sleep mode has been
added and the XE1276A includes non-volatile
memory for storage of the "AT" Commands used
for modem control and configuration.
The XE1276A provides a replacement for the
CH1776. Most OEM's currently using the CH1776
can use the XE1276A without altering their existing
hardware or software. The XE2476 provides a
2400 bps upgrade in the same package design.
The XE1276A includes user transferable FCC Part
68 registration. This permits use of the XE1276A
without additional FCC Part 68 testing.
