DESCRIPTION  
OUTLINE & DIMENSIONS  
GP series VCXOs use fundamental mode (inverted mesa) crystal to  
achieve wide frequency deviation with stable and clean signals. No  
multiplier, overtone crystal or phase lock loop technique is used. As a  
result Jitter is as low as for instance 1ps for the 155.520 MHz for  
SONET/SDH application. Additionally, the inherent advantages of  
differential PECL ECL signal transmission provide improved noise  
immunity making the system less susceptible to ground noise.
