Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open-drain.
3. V
IH
and V
OH
may experience excursions above V
CC
. However, input signal drivers must comply with the
signal quality specifications in Chapter 3.
4. The V
CC
referred to in these specifications refers to instantaneous V
CC
.
5. This specification applies to the asynchronous GTL+ signal group.
6. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load shown in Figure 6.
7. Refer to the processor I/O Buffer Models for I/V characteristics.
8. Vol max of 0.270 Volts is guaranteed when driving into a test load of 50 Ω as indicated in Figure 6 for the
Asynchronous GTL+ signals.
9. Leakage to V
SS
with pin held at V
CC
.
10.Leakage to V
CC
with pin held at 300 mV.
11.For a platform to be forward compatible with future portable processors it must be designed to support an
Ron value of 8.4 Ω (min) and 13.2 Ω (max). A compatible platform is one that is designed for some level of
compatibility with future Portable processors.
