HDMI 2.1 Tx PHY IP in 12FFC

Description and Features

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, 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.HDMI-2.1-Tx-PHY-Controller-IP-supplier-in-china
