Electrical Specifications
NOTES:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
GTLREF is to be generated from V
TT
by a voltage divider of 1% resistors. If an Adjustable
GTLREF circuit is used on the board (for Quad-Core processors compatibility) the two
GTLREF lands connected to the Adjustable GTLREF circuit require the following:
GTLREF_PU = 50
Ω
, GTLREF_PD = 100
Ω.
3.
R
TT
is the on-die termination resistance measured at V
TT
/3 of the GTL+ output driver.
4.
COMP resistance must be provided on the system board with 1% resistors. COMP[3:0] and
COMP8 resistors are to V
SS
.

Clock Specifications
2.8.1
Front Side Bus Clock (BCLK[1:0]) and Processor Clocking
BCLK[1:0] directly controls the FSB interface speed as well as the core frequency of the
processor. As in previous generation processors, the processor’s core frequency is a
multiple of the BCLK[1:0] frequency. The processor bus ratio multiplier will be set at its
default ratio during manufacturing. The processor supports Half Ratios between 7.5
and 13.5, refer to
for the processor supported ratios.
The processor uses a differential clocking implementation. For more information on the
processor clocking, contact your Intel field representative.
