Product Information

www.DataSheet4U.com XE5690SM June 2005 Compact, Low-Cost Global Embedded Modem Description The Xecom XE5690SM provides a complete, global modem as a compact module. Only Xecom offers embedded modems in both through-hole and surface-mount form. User transferable FCC Part 68 registration comes with every Xecom modem. This allows the system designer to add a modem to a process control, remote monitoring, point-of-sale, or remote diagnostic system without Part 68 certification. The XE5690SM footprint is 20% smaller than the most popular embedded modems. The surfacemount version frees additional space on the bottom of the application board. The space efficient design allows the development engineer greater flexibility in placement of the modem within the host system. Xecom offers two interchangeable models: The XE2422SM offers low speed connectivity at low cost; the XE5692SM permits fast V.92 connections.

FCC Part 68 Rules require a 1500 volt isolation barrier between the telephone line and all other circuits. This isolation must be preserved throughout the system. The telephone company places a DC “Battery” voltage across Tip and Ring on public switched telephone lines. The XE5690SM operates regardless of the polarity of this voltage. The “Battery” voltage drives up to 100 milliampere of DC loop current. UL60950 requires minimum creepage and clearances distances between the Tip and Ring and all other circuits. Clearance is the shortest distance between conductive circuits; creepage is the distance between conductive points along the surface 2 Ring The Ring and Tip signal...
