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.
