A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended. 2. Figure 3 defines these parameters. Figure 4 illustrates the operating conditions under which these parameters are tested and specified. For Fo>90MHz, rise and fall time is measured 20 to 80%. 3. Symmetry is measured defined as On Time/Period. 4. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration. 5.
