Product Information

www.DataSheet4U.com XE5690H June 2006 Half-Size, Low-Cost Global Embedded Modem Description The Xecom XE5690H is a complete, global modem in a compact, surface-mount module. It covers less than half the board space of the leading competitor and is less than half as thick as well. Xecom includes user transferable FCC Part 68 registration with every modem module. 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. Only Xecom offers embedded modems in leadless, surface-mount form. As a result, the XE5690H is not only substantially smaller than the competition but the surface-mount package frees additional space on the bottom of the application board for routing traces or placing components. This space efficient design allows the development engineer greater flexibility in placement of the modem within the host system. Features • Models: XE5690H: 0 to 70C operating temp XE5690H-ITR: -40 to 85C operating temperature • Size: 1.6” x 0.8” x 0.152” • Data transfer at rates from 300 bps to 56 Kbps • Control & configuration via AT commands. • 3.3 and 5 volt compatible serial interface • V.42 error control and V.42bis data compression. • Shared line features prevent modem operation from interfering with voice communications. • Boot command automatically loads user defaults • Complete integrated DAA. • User transferrable FCC Part 68 registration • World-wide telephone networks compliance. • UL60950 Recognition • Low Power operation, 3.3 Volts, 100 milliwatts; • RoHS compliant XE5690H BLOCK DIAGRAM XECOM (1) XE5690H XE5690H Mechanical Specifications XECOM (2) XE5690H XE5690H Pin Configuration Top View Tip 1 Ring 2 17 16 N/C N/C 15 /DSR 3 /DCD 4 /DTR 5 /RI 6 SPKR 7 GND 8 14 13 12 11 10 9 /RTS VCC /INT /CTS /RESET RXD TXD Pin Descriptions PIN 1 NAME Tip DESCRIPTION The Ring and Tip signals connect the modem to the telephone line. 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 XE5690H 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 signals connect the modem to the telephone line.

XECOM (3) XE5690H XE5690H Pin Descriptions (continued) PIN 3 4 NAME /DSR /DCD DESCRIPTION /DSR is an active low output from the modem and is forced to the active condition. /DCD is an active low output from the modem. An active /DCD indicates the presence of a valid carrier signal. The AT&C command controls when the XE5690H asserts /DCD. /DTR is an active low input to the modem. An active /DTR signals the terminal is available for communications. The AT&D command determines how the modem interprets activity on /DTR. The /RI signal reports on the presence of an incoming ring signal. When a r...
