2.10.3 V
CACHE
Overshoot Specification
The Dual-Core Intel Xeon processor 7100 series can tolerate short transient overshoot
events where V
CACHE
exceeds the V
CACHE
maximum loadline voltage when transitioning
from a high-to-low current load condition. This overshoot cannot exceed V
CACHE_MAX
+
VOS_cache_MAX. (VOS_cache_MAX is the maximum allowable overshoot above
V
CACHE_MAX
at the low current load). These specifications apply to the processor cache
voltage as measured across the
V
CC_CACHE_SENSE
and V
SS_CACHE_SENSE
pins.
Note:
1. V
CACHE_MAX
is defined in Tab l e 2- 1 2 and Ta b le 2- 13 where I
CACHE
is the low, ending current of the high-to-
low current load condition.
