The power supply should have by-pass capacitors as close to the supply and to ground as possible, for example 0.1 and 0.01uF.
1]
Parameters are tested with production test circuit below , Figure 1.
2]
See Standard Frequencies and Ordering Information tables for more specific information.
3]
Includes initial accuracy, operating temperature, supply voltage, shock and vibration (not under operation) and aging for 50 and 100ppm options.
4]
Duty Cycle is measured as On Time/Period (Fig 2).
5]
Broadband Period Jitter measured using Wavecrest SIA3300C, 90K samples, see Application Note for Typical Phase Noise and Jitter Performance.
