3.3V Surface Mount
5x7.5mm LVDS VCXO
The Connor Winfield model
V514 is a 3.3V, Surface
Mount 5x7.5mm, Voltage
Controlled Crystal Oscillator
(VCXO) with LVDS
differential outputs and a enable/ disable
function. The V514 is designed for use with
applications requiring very high frequency, low
jitter and low phase noise. The surface mount
package is designed for high-density mounting
and is optimum for mass production.

Notes
1.0 Frequency stability vs. change in temperature relative to the frequency measured @ 25°C.
2.0 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.
3.0 When oscillator is disabled both output are in a high impedance state (Tri-State)
4.0 Vod measured with 100 ohm resistor between the true output and the complementary output.
5.0 Duty Cycle measured at 50% of output swing.
