VCXO
The Connor-Winfield, RoHS compliant, V831 is a
3.3V Voltage Controlled Crystal Oscillator (VCXO)
with LVCMOS output and enable/disable function.
The V831 is designed for use with applications utiliz-
ing a PLL system requiring low jitter and tight fre-
quency stability. The surface mount package is
designed for high-density mounting and is optimum
for mass production.

Notes:
1. Includes initial tolerance, deviation over temperature, supply and load variations, shock, vibration and first year.
2. 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.
3. Measured from pin 1 to ground.
4. Outputs are enabled with no connection on pad 2.
