Designed to meet today's requirements for
3.3V Differential LVPECL applications.
The CVPD-920 is produced using our cost
saving FR5 PCB and UM-1 overtone
crystal technology.
This design offers
considerable cost savings over other HFF
VCXO products when broad frequency
pulling is not required. Also available in 14
pin dip fully hermetic package.
