Description Features:

5.0x7.0mm

Surface Mount LVDS

Clock Oscillator Series

The Connor Winfield Lxxx - Series

is a 5x7.5mm 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.
