General Description:
What loads should I use when calculating maximum clock-to-out timing?
The 5.0v PCI specification calls for the output buffer to be loaded with 50pF when clock-to-out timing is measured.
The 3.3v PCI specification (including the 66MHz spec) calls for the output buffer to be loaded with 10pF with a 25 ohm resistor in parallel.
