Power Characteristics
NOTES:
1. The hub interface and CSA interface supply currents are included in the 1.5 V VCC core supply current.
2. VCC and VCC_AGP current levels may happen simultaneously and can be summed into one 1.5 V supply.
3. This specification applies to the GMCH using integrated graphics.
6.4
Signal Groups
The signal description includes the type of buffer used for the particular signal:
AGTL+
Open Drain AGTL+ interface signal. Refer to the AGTL+ I/O
Specification for complete details. The GMCH integrates most AGTL+
termination resistors.
AGP
AGP interface signals. These signals are compatible with
AGP 2.0 1.5 V
and AGP 3.0 0.8V Signaling Environment DC and AC Specifications
. The
buffers are not 3.3 V tolerant. (DVO signals use the same buffers as AGP)
HI15
Hub Interface 1.5 V CMOS buffers.
SSTL_2
Stub Series Terminated Logic 2.6 V compatible signals. DDR system
memory 2.6 V CMOS buffers.
Miscellaneous
2.6 V and 3.3 V Miscellaneous buffers.
