Thank you very much for the information

I haven't tried those values yet, because I thought that with a CLKIN frequency of 6.86 MHz (CLKIN = 145.8ns) for a horizontal line (408*CLKIN = 59,475 us) is out of the range specified in the page 30 (HSD period time : 60us-67us).

Is it ok to have a HSD period time of 59,475 us????

Yes, I checked out the datasheet of the driver, but the only information I found was that the operating frequency of the device for a 24 bit RGB Mode is strictly 6.4 MHz with a HSYNC period (Th)of 408 CLKIN in a time range between 60 usec to 67 usec (Page 26 - Data Active Area and Page 30 - HSD period time), but there is no more information about the implementation of a CLKIN frequency different than 6.4 MHz for a 24 bit RGB Mode, neither the info regarding HSYNC front porch / back porch or VSYNC front porch/ back porch.

In my design, the fixed CLKIN frequency provided to the driver is 6.86 MHz, so it means it is incorrect for the proper use of the device? what is the range of CLKIN frequency allowed by the device? is my design limited to a HSD period time (Th) between 60 usec to 67 usec or are those limitations valid just for a specified CLKIN frequency?

Can you lead me to know how did you get the info regarding to the following data (in the link http://www.newhavendisplay.com/app_notes/NT39016D.pdf, it is not explicitly specified)?

         PARAMETER                   VALUE
Horizontal Front Porch         70 CLKIN
Horizontal Back Porch          18 CLKIN
Vertical Front Porch              13 CLKIN
Vertical Back Porch               10 CLKIN

Good afternoon, I am currently working with NHD-3.5-320240MF-ATXL#-T-1 TFT LCD Display module, and I cannot find the information regarding how many pixel clock cycles are allowed per horizontal line, neither the specific Horizontal Sync back porch and front porch or Vertical Sync back porch and front porch. I couldn't find this info in the product datasheet and I would really appreciate your support in this matter.

The pixel clock frequency I am using is 6,85714 MHz

Best regards
