System Bus Signal Groups
To simplify the following discussion, the system bus signals have been combined into groups by
buffer type. AGTL+ input signals have differential input buffers that use GTLREF as a reference
level. In this document, the term “AGTL+ Input” refers to the AGTL+ input group as well as the
AGTL+ I/O group when receiving. Similarly, “AGTL+ Output” refers to the AGTL+ output group
as well as the AGTL+ I/O group when driving.
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 that are dependent on the rising edge of
BCLK0 (ADS#, HIT#, HITM#, etc.), and the second set is for the source synchronous signals that
are relative to their respective strobe lines (data and address), as well as the rising edge of BCLK0.
Asychronous signals are still present (A20M#, IGNNE#, etc.) and can become active at any time
during the clock cycle. Table 2-3 identifies which signals are common clock, source synchronous,
and asynchronous signals.
NOTES:
1. Refer to Section 5.2 for signal descriptions.
2. These AGTL+ signals do not have on-die termination. Refer to Section 2.5 and the ITP700 Debug Port
Design Guide for termination requirements.
3. In processor systems where there is no debug port implemented on the system board, these signals are used
to support a debug port interposer. In systems with the debug port implemented on the system board, these
signals are no connects.
4. These signal groups are not terminated by the processor. Refer to Section 2.5, the ITP700 Debug Port
Design Guide, and the appropriate Platform Design Guide for termination requirements and further details.
5. The value of these pins during the active-to-inactive edge of RESET# defines the processor configuration
options. See Section 6.1 for details.
