Introduction
1.2.4.2
1.2.4.3
Note:
1.2.5
1.2.6
• The two x8 PCI Express ports can operate in GEN1 or GEN2 mode independent of
each other.
• Supports “static” lane numbering reversal.
— Does not support “dynamic” lane reversal, as defined (optional) by the PCI
Express Specification.
• Supports L1 ASPM power management capability.
sDVO Multiplexed Interface (Intel^® 82Q45, 82Q43, 82B43, 82G45,
82G43, 82G41 GMCH Only)
The GMCH supports two multiplexed SDVO ports that each drive pixel clocks up to
270 MHz. The GMCH can make use of these digital display channels via an Advanced
Digital Display card (ADD2) or Media Expansion card.
HDMI/DVI/DP Multiplexed Interface (Intel^® 82Q45, 82Q43, 82B43,
82G45, 82G43, 82G41 GMCH Only)
The GMCH supports two multiplexed digital display ports that each drive pixel clocks up
to 165 MHz. The GMCH Supports combinations of DP/DP, DVI/DVI, HDMI/HDMI*, DP/
DVI, HDMI/DVI, and DP/HDMI multiplexed on the 2 digital display ports.
Only one channel can support embedded audio at a time.
Graphics Features (Intel^® 82Q45, 82Q43, 82B43, 82G45,
82G43, 82G41 GMCH Only)
The GMCH provides an integrated graphics device (IGD) delivering cost competitive 3D,
2D and video capabilities. DX10 and OpenGL 2.1 are supported. The GMCH contains an
extensive set of instructions for 3D operations, 2D operations, motion compensation,
overlay, and display control. HD-DVD and Blu-Ray are also natively supported with
hardware based VC-1, MPEG2, and AVC decode capabilities. The GMCH also supports
PAVP (Protected Audio-Video Path), which allows for protected Intel^® HD Audio HD
Video Playback.
The GMCH uses a UMA configuration with DVMT for graphics memory. The GMCH also
has the capability to support external graphics accelerators via the PCI Express
Graphics (PEG) port but cannot work concurrently with the integrated graphics device.
High bandwidth access to data is provided through the system memory port.
(G)MCH Clocking
• Differential host clock of 200/266/333 MHz. The (G)MCH supports FSB transfer
rates of 800/1066/1333 MT/s.
• Differential memory clocks of 333/400/533/600 MHz. The (G)MCH supports
memory transfer rates of DDR2-667, DDR2-800, DDR3-800, and DDR3-1067.
• The PCI Express* PLL of 100 MHz Serial Reference Clock generates the PCI Express
core clock of 250 MHz.
• Display timings are generated from display PLLs that use a 96 MHz differential non-
spread spectrum clock as a reference. Display PLLs can also use the
sSDVO_TVCLKIN[+/-] from an SDVO device as a reference. (82Q45, 82Q43,
82B43, 82G45, 82G43, and 82G41 GMCH only)
• All of the above clocks are capable of tolerating Spread Spectrum clocking.
• Host, memory, and PCI Express PLLs are disabled until PWROK is asserted.
