Description
The Connor Winfield model
P234 is a 3.3V, Surface Mount
5.0x7.0mm, Crystal Controlled
CW
0737
155.52MP2H3z4
Oscillator (XO) with LVPECL
differential outputs and a
enable/ disable function. The P234 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) 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 2.
3) Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.
4) Duty Cycle measured at 50% of output swing.
