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
®
Flexible Display Interface (Intel
®
FDI)
For SKUs with graphics, Intel FDI 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
