Notes
1) Includes calibration, stability vs. tem perature, supply and load variations, shock, vibration and aging (10 years).
2) When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state (VoH)
3) Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.
4) Duty Cycle measured at 1.977V
