frequency stability, wide temperature range and low
jitter. Operating at 2.5 or 3.3 Vdc supply voltage,
the LGFxxx series provides LVDS output logic, the
PGFxxx series provides LVPECL and XGFxxx series
provides LVCMOS. The Enable / disable (OE) function
is available on pad 1 or 2. The surface mount package
is designed for high-density mounting and is optimum
for mass production.

Notes
Absolute Ratings: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only. The functional operation
of the device at those or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to conditions outside the "recommended
operating conditions" for any extended period of time may adversely impact device reliability and result in failures not covered by warranty.

1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and vibration and 20 years aging.
2. When the oscillator is disabled the outputs go to tri-state level (high impedance) which floats to VOL. Outputs are enabled with no connection on E/D pad.
3. Vod is measured with a 100 ohm resistor between the true and the complementary outputs.
4. Duty cycle measured at 50% of output voltage swing.
5. Rise and fall times measured from 10% to 90%
6. Outputs must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.
