    1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
    2. Figure 7 defines these parameters. Figure 8 illustrates the operating conditions under which parameters are tested/specified.
    3. Overtone designs, output frequencies>35MHz.
    4. Symmetry is measured defined as On Time/Period.
    5. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under
    operation).
    6. Output will be enabled if enable/disable is left open.
