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 1 defines these parameters. Figure 2 illustrates the operating conditions under which

these parameters are tested and specified.

3. Symmetry is measured defined as Vs, On Time/Period.

4. Includes calibration tolerance, operating temperature, supply voltage variations, aging (40 degreesC/10 years) and shock and

vibration (not under operation). Aging budget is +/-5 ppm.

5. Output w ill be enabled if enable/disable is left open. Output frequency=106M250 if FREQ is left open.

Test Circuit Notes:

1) To Permit 50Ω Measurement of Outputs, all DC Inputs are Biased Down 0.5V.

2) All Voltage Sources Contain Bypass Capacitors to Minimize Supply Noise.

3) 50Ω Terminations are Within Test Equipment.
