PCI Signal DC Characteristics
The following table summarizes the DC characteristic parameters for all PCI signals listed below as they apply to
the S5920.

Notes:
1. Recommended values for all PCI signals except CLK to be Vih = 2.4 Min and Vil = .4 Max.
2. Input leakage applies to all inputs and bi-directional buffers.
3. PCI bus signals without pull-up resistors will provide the 3 mA output current. Signals which require a pull-up resistor will provide 6 mA output
current.
4. The PCI specification limits all PCI inputs not located on the motherboard to 10 pF (the clock is allowed to be 12 pF).
