Description
Features
The Connor-Winfield models V777,
V778, V787 and V788 are 3.3V, Surface
Mount 5.0x7.0mm, Voltage Controlled
Crystal Oscillator (VCXO) with LVPECL
differential outputs and enable/disable
function. The V777, V778, V787 and V788 are designed
for use with applications utilizing a PLL system requiring
very high frequency and low jitter. The surface mount
package is designed for high-density mounting and is
optimum for mass production.
