Description:  
The Connor-Winfield LMxxx - Series  
155.52  
Model LMxxx - Series  
MHz  
5 x7mm Surface Mount Package  
2.5 or 3.3 Vdc Operation  
are 5x7mm Surface Mount, LVDS, Fixed  
Frequency Crystal Controlled Oscillator  
2111 Comprehensive Drive  
LVDS Differential Outputs  
(XO). The LMxxx - Series are designed for  
applications requiring tight frequency stability,  
wide temperature range, and low jitter. Operating  
at 2.5 or 3.3 Vdc supply voltage, the LMxxx -  
Series provides LVDS Differential Outputs with an  
enable / disable function. The design utilizes PLL  
multiplication to produce a high frequency output  
from a low frequency fundamental crystal.  
Frequency Stabilities Available:  
+/-20 ppm, +/-25 ppm, +/-50 ppm or +/-100 ppm  
Temperature Ranges Available:  
0 to 70°C, -40 to 85°C, 0 to 85°C or -20 to 70°C  
Low Jitter <1ps RMS
