• Description: Power PC 440GX Embedded Processor
• Manufacturer: AMCC [Applied Micro Circuits Corporation]

I/O Specifications—All Speeds
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
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.
