Measurement taken from a single-ended waveform.
Measurement taken from a differential waveform.
Measured at the crossing point where instantaneous voltages of both CLKOUT and CLKOUT are equal.
CLKOUT pins are tri-stated when OE is asserted low. CLKOUT is driven differential when OE is high unless its PD= low.
