DP/eDP

Overview

The DP/eDP IP is designed for transmitting or receiving video and audio signals between the video source devices and display devices. It is fully compliant with DP1.4 and eDP1.4 specifications. The IP provides both PHY and controller solutions, offering a reliable implementation for DisplayPort and embedded DisplayPort interfaces that can be seamlessly integrated in the SoCs used in multimedia devices.

The eDP/DP TX IP transmits video, audio, and auxiliary data from a video source device to a display device. It consists of a digital controller and a physical layer. The digital controller processes the input video and audio data and outputs encoded data to the physical layer. The physical layer includes the main link, the AUX channel, a PLL, and a bias circuit, which convert the parallel data to a serial stream.

The eDP/DP RX IP receives and recovers video and audio data from a DP/eDP source device. It also comprises a physical layer and a digital controller. The physical layer converts the received serial stream to parallel data and outputs it to the digital controller. The digital controller decodes the parallel data and recovers the video and audio information.
