HDMI 2.1 Rx PHY IP in 28HPC+

Description and Features

The HDMI V2.1 Rx complies with version 2.1 of the HDMI specification and offers a full single-link HDMI receiver function. It is made up of two modules: a link module and a physical layer (PHY). The connection module is implemented as a synthesizable soft IP, whilst the PHY is upper compatible with the DVI receiver and implemented as a hard IP. The transmission of audio-visual content is secured by an integrated High-bandwidth Digital Content Protection (HDCP) encryption function.
