Parameter
Note 1: Test setup is R
Note 2: Measurement taken from a single-ended waveform.
Note 3: Measurement taken from a differential waveform.
Note 4: Measured at the crossing point where instantaneous voltages of both CLK and CLK are equal.
Note 5: CLK pins are tri-stated when OE is low asserted. CLK is driven differential when OE is high.
Note 1: Guaranteed by design and characterization, not 100% tested in production.
Note 2: See http://www.pcisig.com for complete specs.
