DESCRIPTION
The Connor Winfield P721 is a
Fixed Frequency, Surface Mount
Crystal Controlled Oscillator (XO)
designed for applications
requiring low jitter and a ±50ppm,
-10 to 70°C overall stability,
LVPECL Differential Outputs and
Tri-state Enable / Disable
function. The P721 is designed
using a 2X or 4X PLL
multiplication to achieve the high
frequency output.

Hermetically sealed ceramic package and metal cover.
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.
