PCI Signal DC Characteristics

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

the S5920.

AD[31:0] (t/s), PAR (t/s), C/BE[3:0]# (in), FRAME# (in), IRDY# (in), TRDY# (s/t/s), STOP# (s/t/s), LOCK# (in),

IDSEL (in), DEVSEL# (s/t/s), PERR# (s/t/s), SERR# (o/d), INTA# (o/d), RST# (in), CLK (in).

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).
