TABLE 2.0
NOTE
The Connor-Winfield P731 is a
3.3V Crystal Oscillator (XO) with
LVPECLDifferential outputs and
enable/disable function. The
P731 is designed using a 2X or
4X PLL multiplication to achieve
the high frequency output.

ORDERING INFORMATION
Notes
1) Includes calibration @ 25°C, frequency stability vs. 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.
