The Connor-Winfield VPLD54TEM is a 3.3V  
Voltage Controlled Crystal Oscillator (VCXO)  
with Differential LVPECL outputs and Enable/  
Disable function. The VPLD54TEM is designed  
for use with PLL systems in SONET/SDH sys-  
tems requiring low jitter and tight stability. No  
uses of multiplication schemes are used in this  
oscillator design.
