CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield V762 is a 3.3V
Voltage Controlled Crystal Oscillator
(VCXO) with LVPECL
Differential outputs and
enable/disable function. The V762
is designed for use with applications
utilizing a PLL system requiring low
jitter and tight frequency stability.
No multiplication schemes are used
in this oscillator design. The
surface mount package is designed
for high-density mounting and is
optimum for mass production.

Notes
1.0
Absolute pull range (APR) is the minimum guaranteed pul l range of the VCXO under all conditions over the lifetime
operation. Including calibration @ 25C, frequency vs. change in temperature, frequency vs. change in s upply 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 output s are in a high impedance state.
