FEATURES
GENERAL SPECIFICATION
DESCRIPTION
The XOPL81 range of factory programmable LVDS oscillators provide
custom frequency and specification oscillators within very short lead times.
The parts are very reliable in use and have stabilities from ±50ppm over
-40° to 85°C. In addition to the stability over operating temperature range
customers may also choose from supply voltages of 3.3 and 5.0 Volts. The
3.3 Volt supply version will drive 2.5 Volt logic arrays.
