Notes:
1. Typical power is measured on a typical process part at a case temperature of +85°C at the specified voltages while running Linux and
test applications that exercise each function with representative traffic (2 PCI Express, 2 Gigabit Ethernet, USB, and Security).
2. DDR2 running at 333MHz., PLB running at 166MHz.
3. DDR2 running at 400MHz., PLB running at 200MHz.
4. DDR2 running at 355MHz., PLB running at 177MHz.
5. DDR2 running at 400MHz., PLB running at 200MHz.

Notes:
1. Maximum power is measured on a best-case process (worst-case power) part at a case temperature of +85°C at the specified voltages
while running Linux and test applications that exercise each function with representative traffic (2 PCI Express, 2 Gigabit Ethernet, USB,
and Security).
2. DDR2 running at 333MHz., PLB running at 166MHz.
3. DDR2 running at 400MHz., PLB running at 200MHz.
4. DDR2 running at 355MHz., PLB running at 177MHz.
5. DDR2 running at 400MHz., PLB running at 200MHz.
