Hi,

How to change at dm6437 capture 960H signal??

My video decoder is 960h supports decoder.

I modified VPSS_CLKCTL register setting and input image size(960*480), but it doesn't work.

Is there any registers setting that I didn't notice?

thanks.

Hi,

Thanks for your post.

There is a below statement in the VPFE guide which means VPFE should run at > 60x2 ie 120Mhz in order to support pixel clock of 60Mhz

"The maximum pixel clock rate is 71 MHZ in Normal mode and 90 MHZ in Turbo mode (generically,
1 ns more than 2× the period of the VPFE clock, or CLKDIV3.)"

DDR CLK and VPFE clock should be configured to run at the same speed.

Kindly validate the same.

Thanks & regards,

Hi Sivaraj K,

Thanks for you response.

My video decoder is 960h supports decoder. It Output signal format is BT 656 and the output frequency is 36 HMZ.

My media processor is TMS320DM6437 and the DDR is MT47H64M16HR-25E_FBGA_84ball from MICRON.

960H can be implemented on DM6437?
