The standard HDMI connector is called type A and has 1. Out of the 1. 9 pins, 8 are of particular interest as they form 4 TMDS differential pairs to transport the actual high speed video info.

FPGA pins configured as 4 differential TMDS outputs. Video signal. Lets create a 6. RGB 2. 4bpp 6. 0Hz video signal. Thats 3. 07. 20. Hz, the HDMI link transports 0. Gbps of useful data. But video signals usually also have an off screen area, which is used by the HDMI receiver TV or monitor for some housekeeping. Our 6. 40x. 48. 0 frame is actually sent as an 8. With that in mind, we need a 2. MHz pixel clock to achieve 6. HDMI specifies a 2. MHz minimum pixel clock, so thats we use which gets us a 6. Hz frame rate. TMDS signals. The FPGA has 4 TMDS differential pairs to drive. First, the TMDS clock is simply the pixel clock, so it runs at 2. MHz. The other 3 pairs transmit the red, green and blue signals, so we get something like that. Things are in fact just a bit more complicated. HDMI requires that we actually massage the data with a TMDS encoder, which scrambles the data and add 2 bits per color lane. The scrambling and extra bits are needed by the HDMI receiver to properly synchronize to and acquire each lane mode details in the DVI and HDMI specifications. Source code. First a video generator.

With 6. 40x. 48. 0, we used 2. MHz clocked serializers, but for higher resolutions, we need higher frequencies, which can quickly go above the ability of FPGAs. The workaround is to use some special FPGA IO features, like DDR outputs and IO serializers. Another problem at higher frequencies is how to reliably transfer data from the pixel clock domain to the serializer domain. One possible technique is to use a shallow FIFO. Check the Xilinx XAPP4. Spartan 3. A and XAPP4. Spartan 6 application notes to get some ideas. Screenshots. Here are a few shots made using a digital camera shooting an LCD monitor driven by Pluto IIx HDMI. We have the pong game. Pac. Man arcade game. You can still get the original source using the wayback machine. Heres a pic of our test board Pluto IIx HDMI loaded with an optional HDMI adapter so we actually have two HDMI outputs to play with.
