ADV7181C Register Settings for STANAG3350 Signals

Hi,

  Please refer this document for PLL settings https://www.analog.com/en/resources/app-notes/an-0978.html

Thanks,

Poornima

Thank you Poornima,

But this document is not for ADV7181C. Does it matter?

My main question was why does Table 11 in the User Manual of ADV7181C does not list a lines per frame of 625?

Thanks and regards,

Paul

Hi,

   Yes, We can use this application note(AN-0978) for configuring the non standard mode.

   In 'Table 11' we have the PLL Recommended settings for 625 total lines (Lines per frame 625 total lines (576 Active lines)). Please check

Thanks,

Poornima

Hi Poornima,

Thanks, the highlighted value in the above table is for progressive scan, right?

Shouldn't we use one of them from last two items in the table?

Thanks and regards,

Paul

Hi,

  Yes, you can use the last two items; I just highlighted them for 576p.

Thanks,

Hi Poornima,

We tried that option also still seeing some pixel jittering/shivering mainly where white to black transition is there and the frequency of vibration is varying with two frequencies at the order of a few Hz. Faster frequency for about 10s and other frequency for about 6 seconds.

As mentioned this is visible at the boundaries where contrast is there. Will you be able to throw some lights here?

Strangely, this is observed only for PAL signals and not observed (or not that much visible) for NTSC based signals.

Thanks and regards,

Paul 

Hi,

 Instead of autodetect, Please force the specific video standard according to the below 'VID_SEL' configuration,

 Also If possible, kindly share your register configuration.

Thanks,

Poornima

Hi Poornima,

Below are the register settings we use.

Thanks and regards,

Paul

Hi,

  Kindly note that, Some of the above shared configurations seem to be different form our reference one So Please cross-check your configuration against our reference script - '##CP 625i##' at ez.analog.com/.../5355.ADV7181C_5F00_Evaluation_5F00_Software.zip

Thanks,

Poornima 

Hi Poornima,

Thank you for sharing it.

Could you please be more specific about the file. I was not able to open the .set files.

Does the text file included in the ZIP file has this register details? It has many settings.

I am confused about the very first register itself.

Reg 0x00, INPUT CONTROL register, what we should select for STANAG 3350 B signals. Even though it follows PAL based timings, it is actually Component Video right? Then how should we select the CVBS composite input?

Thanks and regards,

Paul
