FMC-HDMI Card
The FMC-HDMI card contains two HDMI input ports. The first port, HDMI1, contains an ADI ADV7611 Receiver and outputs a decoded, level translated digital video signal to the FMC connector. The second port, HDMI2, contains an ADI AD8195 Buffer and outputs an HDMI-encoded signal to the FMC connector, leaving the system board to decode the signal (either in the FPGA or an external receiver).
The appropriateness of the HDMI port depends entirely on the application. For instance, although HDMI2 does not decode the signal, it outputs to a smaller number of pins (14 instead of 36), which is useful in designs with limited input availability. Since the decoding must be done on the connected system board, the circuitry must support HDMI-type signaling that is TMDS. For example, Xilinx® FPGA families support the TMDS_33 input standard in 3.3Vpowered I/O banks.
