Product Information

XE3386L 12/00 Compact 33,600 BPS Data and Fax Modem Description Xecom's XE3386L combines high-speed data and Group III send/receive fax in a compact component. Xecom designed the XE3386L to be embedded by OEM designers. Xecom also offers pin compatible 2400 BPS 14,400 BPS and 56 KBPS alternatives to the XE3386L for applications with other date rate requirements. The XE3386L is not a modem chip but a complete modem including the telephone interface integrated into a compact module. It provides user transferable FCC Part 68 registration and can connect directly to the telephone line through an RJ11 jack. The modem connects to the host through a TTL level serial interface. The XE3386L also includes MNP2-4, MNP10 and V.42 error control and MNP5 and V.42bis data compression to provide an error free connection with the greatest possible data throughput rate. Features • • • • • • • • • • Small Size; 1.385 " x 1.36" x 0.575" Modem control with "AT" commands Class 1 Fax commands Data transfer up to 33,600 bps Send and receive fax to 14,400 bps MNP and V.42 Error Control MNP10 Error Control for Cellular Links MNP5 Data Compression to 67,200 bps V.42bis Data Compression to 115,200 bps Low power, single +5V supply Operating Power 800 mW (Typ.)

A 1500 volt barrier isolates Ring from all other circuits. This isolation must be preserved throughout the system. The battery voltage on Ring may be positive or negative with respect to Tip. Tip provides half of the two-wire connection to the telephone network, RJ-11 Pin 3. A 1500 volt barrier isolates Tip from all other circuits. This isolation must be preserved throughout the system. The battery voltage on Tip may be positive or negative with respect to Ring. No Connection should be made to these pins. SPK provides the audio output to a speaker. Speaker output is controlled by the ATL and ATM commands. The input impedance to the speaker driver must be greater than 300 ohms. No Connection TXD provides serial data input from the host. A logic high represents a "Mark" and a low represents a "Space". RXD provides serial data output to the host. A lo...
