Intel NUC D53427RKE Technical Product Specification 1.5 Intel® QS77 Express Chipset Intel QS77 Express Chipset with Direct Media Interface (DMI) interconnect provides interfaces to the processor and the USB, SATA, LPC, LAN, and PCI Express interfaces. The Intel QS77 Express Chipset is a centralized controller for the board's I/O paths. For information about The Intel QS77 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) Direct Media Interface (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® Flexible Display Interface (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). 22

1.5.1
Direct Media Interface (DMI)
Direct Media Interface (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
®
Flexible Display
Interface (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).
