Introduction
1.2.6

Embedded DisplayPort* (eDP*)

• Stand alone dedicated port (unlike previous generation processor that shared pins
with PCIe interface)
®
1.2.7 Intel
• For SKUs with graphics, carries display traffic from the Processor Graphics in the
processor to the legacy display connectors in the PCH
• Based on DisplayPort 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
• Common 100-MHz reference clock
