High Frequency
LVPECL VCXO
Model VL7x4 Series
Description:
Features:
3.3V Operation
The Connor-Winfield VL7x4 series are
5x7mm, 3.3 Vdc LVPECL, Surface Mount,
Voltage Controlled Crystal Oscillator
(VCXO) designed for phase lock loop
applications requiring low jitter and tight
frequency stability. The VL7x4 series
uses multiplication to achieve the final
output frequency. The RoHS compliant
surface mount package is designed for
high-density mounting and is optimum for
mass production.
