OP
1] 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.
2] Parameters are tested with the test circuit shown Figure 1.
3] See Standard Frequencies and Ordering Information tables for more specific information.
4] Includes initial accuracy, operating temperature, supply voltage, shock and vibration (not under operation) and aging.
5] Duty Cycle is measured as On Time/Period, see Fig 2.
6] Broadband Period Jitter measured using Wavecrest SIA3300C, 90K samples.
7] The Output is Enabled if the Enable/Disable is left open.
