5x7mm  
Precision TCXO  
Model D75A  
Description:  
Features:  
•ꢀ3.3ꢀVdcꢀOperation  
The Connor-Winfield’s D75A is a 5x7mm  
Surface Mount Temperature Compensated  
Crystal Controlled Oscillator (TCXO) with a  
Tri-State LVCMOS output. Through the use  
of Analog Temperature Compensation, the  
D75A is capable of holding sub 1-ppm sta-  
bilities over the 0 to 70°C temperature range.  
The D75A meets STRATUM 3 requirements.
