The Connor Winfield models V77
V7 are 3.3V,
Surface Mount 5.0x7.0mm, Voltage
Controlled Crystal Oscillator (VCXO)
with LVPECL differential outputs and enable/ disable
function. The 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.

1.0 Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all
conditions over the lifetime operation. Including calibration @ 25°C, frequency vs.
change in temperature, frequency vs. change in supply voltage, frequency vs. change in
load, shock and vibration and aging for ten years. The APR is referenced to Fo. Positive
Transfer Function.
2.0 Outputs are enabled with no connection on pad 2. When oscillator is disabled both
outputs are in a high impedance state.
