Electrical Specifications
With the implementation of a source synchronous data bus comes the need to specify two sets of
timing parameters. One set is for common clock signals whose timings are specified with respect to
rising edge of BCLK0 (ADS#, HIT#, HITM#, etc.) and the second set is for the source
synchronous signals which are relative to their respective strobe lines (data and address) as well as
rising edge of BCLK0. Asynchronous signals are still present (A20M#, IGNNE#, etc.) and can
become active at any time during the clock cycle. Table 2-4 identifies which signals are common
clock, source synchronous and asynchronous.
NOTES:
1. Refer to Section 4 for signal descriptions.
2. The 64-bit Intel Xeon processor with 2 MB L2 cache only uses BR0# and BR1#. BR2# and BR3# must be
terminated to VTT. For additional details regarding the BR[3:0]# signals, see Section 4 and Section 7.1.
3. The value of these pins during the active-to-inactive edge of RESET# defines the processor configuration
options. See Section 7.1 for details.
4. These signals may be driven simultaneously by multiple agents (wired-OR).
Table 2-5 outlines the signals which include on-die termination (RTT) and lists signals which
include additional on-die resistance (RL). Table 2-6 provides signal reference voltages.
