Notes:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The V
TTA
referred to in these specifications refers to instantaneous V
TTA
.
3. R
SYS_TERM
is the termination on the system and is not controlled by the processor.
4. Applies to all Processor Sideband signals, unless otherwise mentioned in Table 2-6.
5. This specification only applies to DDR_THERM# and DDR_THERM2#signals.
6. COMP resistance must be provided on the system board with 1% resistors. COMP0 resistors are tied to V
