DisplayPort Subsystem


Product Description

The AMD DisplayPort solutions include DisplayPort TX and RX subsystems designed to VESA DisplayPort V1.2 specification and DisplayPort 1.4 TX and RX subsystems to be available in Vivado 2018.1(April 2018) designed to VESA DisplayPort V1.4 specification. These solutions help users implement DisplayPort video interface as defined by VESA DisplayPort specification. DisplayPort is a high-speed serial interface standard supported by industry leaders in consumer electronics HDTV, PC laptop and PC monitors. This protocol is considered a successor to VGA and DVI standards with support for video resolutions up to 8Kx4K video and adds audio.

DisplayPort LogiCORE IP supports UltraScale™ and 7 Series FPGAs.

DisplayPort 1.4 subsystems support supports UltraScale and UltraScale+™ FPGAs and includes support for DisplayPort V1,2 specification also.

To help users in creating video solutions with DisplayPort interfaces, AMD offers prepackaged subsystems for DisplayPort transmit and DisplayPort receive. These subsystems integrate commonly used functions with video interfaces such as video timing generation, AXI bridges and optional HDCP function with DisplayPort LogiCORE and work out of the box.

The standalone DisplayPort LogiCORE in Vivado release 2017.2 has been discontinued and hence users are strongly recommended to use DisplayPort Subsystems for all new designs.
