The DVI Debug Tool provides an easy way to debug HDMI/DVI video signals. This board breaks out the following signals:
- Horizontal Sync (HSYNC)
- Vertical Sync (VSYNC)
- Pixel Clock (PCLK)
- RED Pixel Data (D0-D7)
- GREEN Pixel Data (D0-D7)
- BLUE Pixel Data (D0-D7)
Each of the above signals are brought out to test points where they can be easily probed with an external oscilloscope or logic analyzer.
In additon, you can select the following incoming signal options with a simple jumper:
- Pixel Clock Level Select – select either rising or falling edge
- Pixels Clock – select either one or two pixels per clock.
