Innosilicon 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.

Innosilicon 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.
