LVCMOS VCXO
Specification
Model V855
Description:
The Connor-Winfield, RoHS compliant,
V855 is a 3.3V Voltage Controlled Crystal
Oscillator (VCXO) with LVCMOS output
and enable/disable function. The V855
is designed for use with applications
utilizing a PLL system requiring low jitter
and tight frequency stability. The surface
mount package is designed for high-
density mounting and is optimum for mass
production.
