Notes:

1. For specific junction temperature and voltage-supply levels, refer to Table 3-6 on page 3-7 for derating values.

2. Resistance is used to measure I/O propagation delays as defined in PCI specifications. See Figure 2-121 on page 2-199

for connectivity. This resistor is not required during normal operation.
