1.
V
OS_CACHE
is measured overshoot voltage.
2.
T
OS_CACHE
is measured time duration above Vcache_max.

Die Voltage Validation
Overshoot events from application testing on the processor must meet the
specifications in

CCSENSE
and V
SSSENSE
pins and
when measured across the V
CC_CACHE_SENSE
and V
SS_CACHE_SENSE
pins.
Overshoot events that are < 10 ns in duration may be ignored. These measurements of
processor die level overshoot should be taken with a 100 MHz bandwidth limited
oscilloscope.
