FDI)
• Carries display traffic from the integrated graphics in the processor to the legacy
display connectors in the PCH.
• Based on Display Port standard
• Two independent links—one for each display pipe
• Four unidirectional downstream differential transmitter pairs
— Scalable down to 3X, 2X, or 1X based on actual display bandwidth
requirements
— Fixed frequency 2.7 GT/s data rate
• Two sideband signals for Display synchronization:
— FDI_FSYNC and FDI_LSYNC (Frame and Line Synchronization)
• One Interrupt signal used for various interrupts from the PCH
— FDI_INT signal shared by both Intel FDI Links
• PCH supports end-to-end lane reversal across both links
