I/O Specifications—All Speeds (Sheet 3 of 7)

Notes:

1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.

2. PCI-X timings are for asynchronous operation up to 133MHz. PCI-X input setup time requirement is 1.2ns for 133MHz and

1.7ns for 66MHz. PCI timings (in parentheses) are for asynchronous operation up to 66MHz. PCI output hold time

requirement is 1ns for 66MHz and 2ns for 33MHz.

3. The clock frequency for RMII operation is 50MHz ± 100ppm.

4. The clock frequency for SMII operation is 125MHz ± 100ppm.

5. These are DDR signals that can change on both the positive and negative clock transitions.
