Notes:

1. Characterized across DC supply voltage range.

2. The 2.625-V value is equal to 2.5 V plus a maximum of five percent.

3. Refer to “VCC_2.5V Generation Circuit” found in the section, “Motherboard Required Circuits,” of the AMD Athlon™ Processor- Based Motherboard Design Guide, order# 24363.

4. Edge rates indicate the range for characterizing the inputs.
