CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield P124 is

a fixed frequency, surface

mount Crystal Controlled

Oscillator (XO) designed for

applications requiring low

jitter and a ±50ppm overall

stability. Operating at 3.3V

supply voltage, the P124

provides LVPECL Differential

Outputs with Enable/Disable

function on Pad 2.

Notes

1)

Includes initial tolerance, dev iation over temperature, supply and load variations, shock, vibration and 20 years aging.

2)

When the oscillator is disabled, t he outputs are at High Impedance. Output is enabled with no connect ion on pad 2.

3)

Output must be terminated into 50 ohms t o Vcc – 2V or Thevenin equivalent.

4)

Duty Cycle measured at 50% of output swing.
