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.
