Test setup is R
Measurement taken from a single-ended waveform.
Measurement taken from a differential waveform.
Measured at the crossing point where instantaneous voltages of both CLK and CLK are equal.
CLK and CLK pins are tri-stated when OE is Low asserted. CLK and CLK are driven differential when OE is High
