Datasheet
NOTES:
1.
The voltage specification requirements are defined across at the socket motherboard pinfield vias on the
bottom side of the baseboard.
2.
The voltage specification requirements are defined across VTT_SENSE and VSS_SENSE_VTT pins on the
bottom side of the baseboard.
3.
Defined at nominal VTT voltage
4.
These are pre-silicon estimates and are subject to change.
5.
Based on junction temperature of 50°C.
