1.5 Analog and SDVO Displays (Intel ® 82945G/82945GC/82945GZ GMCH Only) Introduction The GMCH provides interfaces to a progressive scan analog monitor and two SDVO ports (multiplexed with PCI Express x16 graphics port signals on the 82945G/82945GC) capable of driving an ADD2/ADD2+ card. The digital display channels are capable of driving a variety of SDVO devices (e.g., TMDS, TV-Out). Note that SDVO only works with the Integrated Graphics Device (IGD). The ADD2+ card adds Video-in capabilities and is only supported on the 82945G GMCH. The GMCH provides two multiplexed SDVO ports that are capable of driving up to a 200 MHz pixel clock each. The GMCH can make use of these digital display channels via an Advanced Digital Display card (ADD2/2+) card. The GMCH SDVO ports can each support a single-channel SDVO device. If both ports are active in single-channel mode, they can have different display timing and data. Alternatively, the SDVO ports can be combined to support dual channel devices, supporting higher resolutions and refresh rates. The GMCH is compliant with DVI Specification 1.0. When combined with a DVI compliant external device and connector, the GMCH has a high-speed interface to a digital display (e.g., flat panel or digital CRT). The 82945G/82945GC GMCH supports Hot-Plug and Display for the PCI Express x16 graphics. This is not supported for ADD2 cards. 1.5.1 System Interrupts � Supports both 8259 and Pentium 4 processor FSB interrupt delivery mechanisms. � Supports interrupts signaled as upstream Memory Writes from PCI Express and DMI � MSIs routed directly to FSB � From I/OxAPICs � Provides redirection for IPI(Inter-Processor Interrupts) and upstream interrupts to the FSB 1.5.2 (G)MCH Clocking The differential Host clock of 133/200/266 MHz (HCLKP/HCLKN) supports transfer rates of 533/800/1066 MT/s, respectively. The 266 MHz HCLKP/HCLKN is only available on the 82945G GMCH and 82945P MCH. The Host PLL generates 2X, 4X, and 8X versions of the host clock for internal optimizations. The (G)MCH core clock is synchronized to the host clock. The internal and external memory clocks of 200, 266, and 333 MHz are generated from one of two (G)MCH PLLs that use the Host clock as a reference. This includes 2x and 4x for internal optimizations. The PCI Express core clock of 250 MHz is generated from a separate PCI Express PLL that uses the fixed 100 MHz Serial Reference Clock (GCLKP/GCLKN) for reference. 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 SDVO_TVCLKIN[+/-] from an SDVO device as a reference. Intel ® 82945G/82945G/82945GC GMCH and 82945P/82945PL MCH Datasheet 29
