Using the Dynamic Horizontal Resolution (HRES) TX Utility

If your application needs to support changes in resolution for different frames, you need to use an additional calculation to help determine the front and back porch timing values for the HSYNC signal.

  1. Enter values in the MIPI TX tab as described in MIPI Transmitter Settings for one of the resolutions you want to use until it passes.
  2. Click the DYNAMIC HRES GEN tab. This sheet should display "READY TO GEN” when the MIPI TX worksheet passes.
  3. Enter the resolution values you want in the rows under HRES. The utility includes some example values. Delete ones that you do not want and add any additional values.
  4. Click Generate Porch and Max. # of Lines. The utility generates the required maximum and minimum porch values for each resolution.
