Product Description 1.5 Intel® Z77 Express Chipset Intel Z77 Express Chipset with Intel FDI and Direct Media Interface (DMI) interconnect provides interfaces to the processor and the display, USB, SATA, LPC, LAN, and PCI Express interfaces. The Intel Z77 Express Chipset is a centralized controller for the board's I/O paths. For information about The Intel Z77 Express Chipset Resources used by the chipset Refer to http://www.intel.com/products/desktop/chipsets/index.htm Chapter 2 1.5.1 Direct Media Interface (DMI) DMI is the chip-to-chip connection between the processor and PCH. This high-speed interface integrates advanced priority-based servicing allowing for concurrent traffic and true isochronous transfer capabilities. 1.5.2 Display Interfaces Display is divided between the processor and the PCH. The processor houses the memory interface, display planes, and pipes while the PCH has transcoder and display interface or ports. The PCH receives the display data over Intel FDI and transcodes the data as per the display technology protocol and sends the data through the display interface. 1.5.2.1 Intel® Flexible Display Interconnect (Intel® FDI) Intel FDI connects the display engine in the processor with the display interfaces on the PCH. The display data from the frame buffer is processed in the display engine of the processor and sent to the PCH over the Intel FDI where it is transcoded as per the display protocol and driven to the display monitor. 1.5.2.2 High-bandwidth Digital Content Protection (HDCP) HDCP is the technology for protecting high definition content against unauthorized copy or unreceptive between a source (computer, digital set top boxes, etc.) and the sink (panels, monitor, and TVs). The PCH supports HDCP 1.4 for content protection over wired displays (HDMI). 1.5.2.3 High Definition Multimedia Interface* (HDMI*) The HDMI port supports standard, enhanced, or high definition video, plus multichannel digital audio on a single cable. It is compatible with all ATSC and DVB HDTV standards and supports eight full range channels at 24-bit/96 kHz audio of lossless audio formats such as Dolby* TrueHD or DTS* HD Master Audio. The maximum supported resolution is 1920 x 1200 (WUXGA). The HDMI interface supports the HDMI 1.4a specification. 23
