Notes on Electrical Characteristics:
1_{Guaranteed by design and characterization, not 100% tested in production.}
2 _{Slew rate measured through Vswing centered around differential zero}
3 _{Vxabs is defined as the voltage where CLK = CLK#}
4 _{Only applies to the differential rising edge (CLK rising and CLK# falling)}
5 _{Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of CLK}
and falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets CLK#.
The average cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations.
6 _{All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz}
7 _{Operation under these conditions is neither implied, nor guaranteed.}
8 _{Maximum input voltage is not to exceed maximum VDD}
9 _{See PCI Clock-to-Clock Delay Figure}
10 _{At nominal voltage and temperature}
11 _{See http://www.pcisig.com for complete specs}
