AC Electrical Characteristics - CLK0/CLK1, CLK0/CLK1

Unless stated otherwise, VDD=3.3 V ±5%, Ambient Temperature -40 to +85

C

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.

Electrical Characteristics - Differential Phase Jitter

Note 1. Guaranteed by design and characterization, not 100% tested in production.

Note 2. See http://www.pcisig.com for complete specs.
