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.
