AD7181D  RGB Graphics Digitizer Blanking period

We are using AD7181D as an RGB graphics digitizer to convert SVGA analog RGB input signals with horizontal and vertical synchronization input signals into digital output signals to be connected to a liquid crystal monitor using a video pixel output port and a data enable signal (DE).

Please tell us how to set the blanking period of the input signal to AD7181D.


In a production test using AD7181D, we had a problem that the top line was not displayed. We understand that such a problem can be resolved by delaying the blanking period of the SVGA analog RGB output by 1 hour. However, the system does not allow a change in the output, so we’d like to do it to the input.
