Notes:
1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and vibration and 20 years
aging. Models L242, L243, L244 and L245 are not available above 260 MHz.
2. Models L242, L243, L244 and L245 are not available above 260 MHz.
3. When the oscillator is disabled the outputs are at high impedance. Outputs are enabled with no connection on E/D pad.
4. Vod is measured with a 100 ohm resistor between the true and the complementary outputs.
5. Duty cycle measured at 50% of output voltage swing..
