Can I use a transceiver RX Pin as a Tx PLL REFCLK for the HDMI Design Example transmitter interface (Source) on Intel® Arria® 10 and Cyclone®10 devices? - Can I use a transceiver RX Pin as a Tx PLL REFCLK for the HDMI Design Example transmitter interface (Source) on Intel® Arria® 10 and Cyclone®10 devices? Description No, you cannot use a transceiver RX Pin as a Tx PLL REFCLK for the HDMI™ Design Example Transmitter Interface (Source) on Intel® Arria® 10 and Cyclone®10 devices. The HDMI Design Example Transmitter (Source) connects the REFCLK signal to the Tx PLL (fPLL) and an IOPLL used to generate the video clocks. The RX Pin as a REFCLK resource cannot connect to an IOPLL. Your Intel® Quartus® software design will fail to fit if you place the HDMI Design Example TX REFCLK on an Rx Pin. Resolution To work around this problem, place your HDMI Design Example TX REFCLK on a dedicated transceiver REFCLK pin.
