2 Measured from differential waveform

3 Duty cycle distortion is the difference in duty cycle between the output and the input clock when the device is operated in bypass mode.

4 All outputs at default slew rate

5 The MIN/TYP/MAX values of each BW setting track each other, i.e., Low BW MAX will never occur with Hi BW MIN.

4 For RMS figures, additive jitter is calculated by solving the following equation: Additive jitter = SQRT[(total jitter)^2 - (input jitter)^2]

5 Driven by 9FGV0831 or equivalent

6 Driven by Rohde&Schwarz SMA100
