148 Intel® Xeon® Processor E5-1600 v2/E5-2600 v2 Product Families
Datasheet Volume One of Two
Notes:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The voltage rail V
CCD
which will be set to 1.50 V or 1.35 V nominal depending on the voltage of all DIMMs connected to the
processor.
3. V
IL
is the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
4. V
IH
is the minimum voltage level at a receiving agent that will be interpreted as a logical high value.
5. V
IH
and V
OH
may experience excursions above V
CCD
. However, input signal drivers must comply with the signal quality
specifications. Refer to Section 7.9.
6. This is the pull down driver resistance. Refer to processor signal integrity models for I/V characteristics. Reset drive does not
have a termination.
7. R
VTT_TERM
is the termination on the DIMM and not controlled by the processor. Please refer to the applicable DIMM datasheet.
8. The minimum and maximum values for these signals are programmable by BIOS to one of the pairs.
9. COMP resistance must be provided on the system board with 1% resistors. DDR01_RCOMP[2:0] and DDR23_RCOMP[2:0]
resistors are terminated to VSS.
10. Input leakage current is specified for all DDR3 signals.
