Overview
Introduction
The DisplayPort IP-core is a DisplayPort solution for FPGA implementation. It has a resource optimized footprint and it is written in SystemVerilog. A thin host driver is provided with the IP-core. The application software controls the IP-core using this driver.
Features
- DisplayPort 1.4a
- RBR, HBR, HBR2 and HBR3 line rates
- Support for 1, 2 and 4 DP lanes
- Native video and AXI stream interfaces
- Single Stream transport mode (SST)
- Multi Stream transport mode (MST)
- Dual and quad pixels per clock (PPC)
- Color depth: 8 & 10-bits (BPC)
- Color space: RGB 4:4:4 & YUV 4:4:4

Known Limitations
DPTX / DPRX
- The horizontal video timing must be dividable by the number of pixels per clock (PPC).
- Any video resolution is supported, however only video resolutions tested are 720p50/60, 1080p50/60, 1440p50/60 and 4kp50/60.
VTB
- At start of the video the screen might flicker while the clock recovery module is locking to the incoming video stream.
