Part Number: TFP410

Hi,

I have a question about TFP410PAP.

I wan't to know if the TFP410 works normally if my clock (IDCK+) is less than 25MHz?

In my case i want to transmit just 1x image but it doesn't work.

What synchronisation for the different signal, (DE/HSYNC/VSYNC) and the time front porch /back porch, must be respectectly

Thanks

Best regards

Hi Patrick,

As stated in the datasheet, the minimum frequency for the TFP410 is 25MHz. We can't guarantee correct operation if you use frequencies below that.

Hi I.K

Yes i see that in the datasheet but i have no signal on my screen , and i don't know if this problem come of my frequency, my register configuration or my signal synchronisation.

Hi Patrick,

Are you using a frequency below 25MHz? If so that may be issue. I'm not able to help you unless you use the device within the specified operating conditions.
