Hi
Now I have a design aims to convert a coms sensor's digital output to DVI signal. The sensor's output is odd: 8bitYCbCr4:2:2 PixClk:65MHz Hall=2924(PixClk) Heff=2560(PixClk) Vall=735(Line) Veff=720(Line) FieldRate=30. It's different from the CEA-861-E which specified the 720P@30 timing as PixelFreq=74.25MHz Htotal=3300 Hblank=2020 Vtotal=750 Vblank=30. I did not find a chip to accomplish this kind of convertion directly. So I want to use FPGA+TFP410 to do this job.
My question is: does TFP410 depend on the CEA-861-E timing specification? I checked Chrontel's CH7301C which claims "The device is not dependent upon this set of timing specifications. Any values of pixels/line, lines/frame and clock rate are acceptable, as long as the pixel rate remains below 165MHz." in its datasheet, I wonder if TFP410 has the same ability?
If the answer to the second question is positive, can I just convert the sensor's YUV output to RGB signals that TFP410 needed, and use a PixelFreq other than 74.25MHz, say 32.5MHz, to feed the TFP410 (That will reduce my cost,time and work) to generate DVI signal that a LCD monitor can display?
Any help / suggestion would be greatly appreciated!
B.R.
