AGTL+ System Bus Specifications
Routing topology recommendations can be found in the appropriate Platform Design Guide listed
in Table 1. Termination resistors are not required for most AGTL+ signals because termination
resistors are integrated into the processor silicon.
Valid high and low levels are determined by the input buffers which compare a signal’s voltage
with a reference voltage called GTLREF (known as VREF in previous documentation).
Table 15 lists the GTLREF specifications. The AGTL+ reference voltage (GTLREF) should be
generated on the system board using high precision voltage divider circuits. It is important that the
system board impedance be held to the specified tolerance, and that the intrinsic trace capacitance
for the AGTL+ signal group traces is known and is well-controlled. For more details on platform
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The tolerances for this specification have been stated generically to enable the system designer to calculate
the minimum and maximum values across the range of VCC.
3. GTLREF should be generated from VCC by a voltage divider of 1% tolerance resistors, or 1% tolerance
matched resistors. Refer to the appropriate Platform Design Guide listed in Table 1 for implementation
details.
4. RTT is the on-die termination resistance measured at VOL of the AGTL+ output driver. Refer to processor I/O
buffer models for I/V characteristics.
5. COMP resistance must be provided on the system board with 1% tolerance resistors. See the appropriate
Platform Design Guide for implementation details.
6. The VCC referred to in these specifications is the instantaneous VCC.
