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 LVPECLDifferential  
Outputs with a tri-state enable /  
disable function.

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.
