HDMI v2.1 Tx PHY & Controller IP
OverviewFeaturesRequest Datasheet
The HDMI V2.1 Tx provides a complete single-link HDMI transmitter function complies with HDMI specification version 2.1 It consists of two modules, a physical layer and a link module. The PHY is upper compatible with DVI transmitter and implemented as a hard IP based on an TSMC 12FFC process, while the link module is implemented as a synthesizable soft IP. Built-in High-bandwidth Digital Content Protection (HDCP) cipher function protects the transmission of audio-visual contents.
