Septembeer 2005
Low-Cost, 2400 BPS Surface-Mount Modem
Description
XE2422H is a complete miniature, surface-mount,
2400 bps modem. It permits the designer to easily
incorporate dial-up communications into set top
box, security, vending, or point-of-sale applications.
XE2422H is not just a modem chip. The only
design requirements are a serial port connection to
the micro-controller and the connection to the
telephone line. The XE2422H includes transferable
FCC Part 68 Registration eliminating FCC Part 68
testing for the Xecom customer.
With the XE2422H, Xecom lowers the total cost of
modem ownership. As a complete modem, it
dramatically reduces modem development and
certification costs. Assembly costs are reduced as
dozens of components are replaced with this single,
surface-mount module. And since Xecom tests
100% of all modules, quality is also improved. The
cost of the XE2422H is under nine dollars in
100,000 piece quantities. Contact Xecom for
pricing at other quantities
