ADV 7511

Hi everybody,

i am trying to output some very basic HDMI Data with the ADV 7511, however i don't get any signal on my hdmi screen. The plan is to first of all display a blue square in the lower right corner in 480p using a XILINX FPGA. The chip is connected to the FPGA with a 16 Bit wide Databus.

So far I've set all the registers as described in the programming guide in chapter 3 (the quickstart part).

I trust my self implemented 100 kHz I2C configuration, as i have verified the transmission and checked for every acknowledge.

Now the following questions / problems arise:

• When I use the 16 Bit input format as described in Section 4.3.1 with Input Id 1 and Style 1, i need to use two clock cycles for every pixel, right? One for Cb Y and one for CrY
• The polarity of the DE, HSYNC and VSYNC Signals are active low?

With these settings I don't get any output at all. Do you have any idea, what the problem could be?

Best regards
