Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V
IL is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
3. V
IH is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
4. V
IH and VOH may experience excursions above VCCP. However, input signal drivers must comply with the
signal quality specifications in Chapter 4.
5. This is the pull down driver resistance. Refer to processor I/O Buffer Models for I/V characteristics. Measured
at 0.31
x VCCP. R

6. GTLREF should be generated from VCCP with a 1% tolerance resistor divider. The VCCP referred to in these
specifications is the instantaneous VCCP.
7. R
TT
is the on-die termination resistance measured at V
OL
of the AGTL+ output driver. Measured at 0.31 x
VCCP. R
TT
is connected to VCCP on die. Refer to processor I/O buffer models for I/V characteristics.
8. Specified with on die R
TT
and R
ON
are turned off.
9. Cpad includes die capacitance only. No package parasitics are included.
