VCXO
The Connor-Winfield, RoHS compliant, V751 is a
3.3V Voltage Controlled Crystal Oscillator (VCXO)
with LVPECL Differential outputs and enable/disable
function. The V751 is designed for use with applica-
tions 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. Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over the lifetime operation. Including calibration @ 25C,
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. Outputs are enabled with no connection on pad 2. When oscillator is disabled both outputs are in a high impedance state.
3. 50 ohm termination into Vcc-2V or Thevein equivalent.
