X431
DESCRIPTION
The Connor Winfield X431 is a
fixed frequency, surface mount
Crystal Controlled Oscillator (XO)
designed for applications requiring
low jitter and a +/-50ppm overall
frequency stability. Operating at
3.3V supply voltage, the X431
provides LVPECL Differential
Outputs with a tri-state enable /
disable function.

See solder profile page 2.
Notes
1) Includes initial tolerance, deviation over temperature, supply and load variations, shock, vibration and 20 years
aging.
2) When the oscillator is disabled, the outputs are at High Impedance. Output is enabled with no connection on pad 1.
3) Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.
4) Duty Cycle measured at 50% of output swing.
