Model Lxxx - Series

The Connor Winﬁeld Lxxx - Series are

5.0x7.0mm Surface Mount, LVDS, Fixed

Frequency Crystal Controlled Oscillator

(XO) designed for applications requiring

tight frequency stability, wide temperature range

and low jitter. Operating at 2.5V or 3.3V supply

voltage, the Lxxx - Series provides an LVDS

Differential Outputs with enable / disable function.

The surface mount package is designed for

high-density mounting and is optimum for mass

production.
