DP/eDP 1.4 Rx DisplayPort/eDP

DisplayPort 1.4a / eDP 1.4b RX PHY and Controller IP

Overview

Silicon Library (SLI) DisplayPort (DP) 1.4a / Embedded DisplayPort (eDP) 1.4b RX IP cores provide a comprehensive transmitter solution compliant with VESA DisplayPort 1.4a and Embedded DisplayPort (eDP) 1.4b standards, enabling seamless integration into SoCs for modern multimedia applications. The solution consists of two modules: a physical layer (PHY) and a controller (Link Layer / PCS). The PHY is a hard macro supporting high-speed data rates up to 8.1Gbps (HBR3), while the controller is pprovided as a synthesizable soft macro. In addition to required DisplayPort functionalities, the solution supports optional features including Multi-Stream Transport (MST), Display Stream Compression (DSC), Forward Error Correction (FEC) and HDCP 1.4/2.3 content protections can be added to the configurable controller. SLI’s PHY IPs and Controller IPs work together to deliver the best results with simplified integration although SLI’s PHY and Controller IPs can be offered as independent products.
