2.1. HDMI RX with Integrated Transceiver

HDMI RX includes a hard transceiver block that receives the serial data from an external video source. It deserializes the serial data to parallel data before passing the data to the HDMI RX IP core.

The HDMI RX IP core receives the parallel data from the Transceiver PMA Direct PHY and performs data alignment, channel deskew, TMDS decoding, auxiliary data decoding, video data decoding, audio data decoding, and descrambling.

For the RX transceiver (RX Direct PHY), the example design uses System PLL datapath clocking mode. In the figure that follows, rx_clkout is the System PLL clock and rx_clkout2 is Word clock. The parallel data output from the transceiver is driven by the System PLL clock. The design uses DCFIFO to switch the data from System PLL clock domain to the Word clock domain before going into HDMI RX.
