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 GroupsThe signal description includes the type of buffer used for the particular signal:AGTL+AGPHI15SSTL_2MiscellaneousOpen Drain AGTL+ interface signal. Refer to the AGTL+ I/OSpecification for complete details. The GMCH integrates most AGTL+termination resistors.AGP interface signals. These signals are compatible with AGP 2.0 1.5 Vand AGP 3.0 0.8V Signaling Environment DC and AC Specifications. Thebuffers are not 3.3 V tolerant. (DVO signals use the same buffers as AGP)Hub Interface 1.5 V CMOS buffers.Stub Series Terminated Logic 2.6 V compatible signals.
