Power and Thermal
Characteristics
Table 36 provides the derived power and thermal characteristics for the production
version (Revision D0) of the C-5 NP.
Notes for Table 36:
1 Estimated power dissipation (+/-10%) is derived from measurements on the C-5 NP
Revision D00 under following conditions:
BMU memory operating at 125MHz.
TLU memory operating at 133MHz.
V
DD = 1.8V, VDD33 = 3.3V, TJ at approximately 50
o C.
“Minimum” P
D based on idle condition (clocks running and no programs
executing).
“Typical” P
D based on test application that implements Fast Ethernet forwarding
actively running on all CPs.
“Maximum” P
D based on projected maximum consumption for any
high-bandwidth communications application executing on all CPs, FP, and XP.
