VCXO
Description
Features
The Connor Winfield models
V975 and V976 are 3.3V,
Surface Mount 5.0x7.0mm,
Voltage Controlled Crystal
Oscillator (VCXO) with LVDS
differential outputs and enable/ disable
function. The V975 and V976 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.
