DP/eDP1.4/1.2 RX PHY

Overview

Innosilicon DP RX PHY is designed to receive and recover the video, audio and auxiliary data from a DP or eDP source device for display applications. It is composed of physical layer and PHY logic.
? The physical layer contains 4 data channels, an AUX channel and bias circuit.
? The 4 data channels serve as the main link to receive video and audio stream with a data rate up to 8.1Gbps. Each data channel consists of termination, equalizer and CDR circuit.
? The AUX channel employs half-duplex, bidirectional link to transmit and receive auxiliary information, such as EDID information and link status between a transmitter and a receiver device.
? The bias circuit generates voltage and current reference.
? The PHY logic receives the recovered parallel data and clocks signals of 4 data channels.
Innosilicon DP RX IP offers reliable implementation for DP or eDP interface, which can be integrated in the SOC used in multimedia device.
