Surface Mount LVDS  
Clock Oscillator Series  
Description  
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.
