Surface Mount V.34 Telephone Line Interface
Description
Xecom's XE0080 is a miniature, surface-mount
telephone interface module for high-volume
applications. The XE0080 meets FCC Part 68
rules for direct connection to the public telephone
network, supports V.34 data transfer, and adapts
to automated pick and place equipment.
The XE0080 is a complete telephone line
interface. It includes the line transformer, ring
detection, switch hook control and loop current
holding circuit. The XE0080 supplies a 1500 volt
isolation barrier between the telephone line and
the host circuitry.
The XE0080 fits all this circuitry into a package
just 0.80 inches square and 0.200 inches thick.
The 0080 attaches to the board through nine
surface-mount pins.
The XE0080 operates from a single power supply
of either +5 volts or +3.3 volts for low power
applications. It is intended for high volume
applications including set top box and credit
verification systems
