Does adv7513 support 720p30 YCbCr4:2:2 input format and convert to 720p60 output format?

Hi,

ADV7513 cannot convert frame rates from 30Hz to 60Hz.  For that Please look at the ADV8005 for format conversion https://www.analog.com/en/products/adv8005.html

Following VSP features are supported in ADV8005.

Thanks,

Poornima

Hi Poornima,

   Thank you very much! By the way, how to config the HDMI output to 720p30 in this case?

   We tried below setting to config adv7513, but the HDMI was no signal output. Could you please help to review what is the wrong of it?

Hi,

Please make sure with below table for pin assignment according to your configuration. Also let us know why you have configured for 4x pixel clock instead of 2x clock.

Basically the setting are based on pixel rates.  The 720p60 setting should work fine for 720p30. The various 7511 scripts can be found in the AVES3_folder here
Advantiv EVAL-ADV7612-7511 Video Evaluation Board

We don't have a specific script for the ADV7513 running 720p30 over an 8-bit bus however these scripts are for the ADV7511 which is the same die as the ADV7513.  bt656-ADV7842_7511-hdmi.txt.zip

Hi Poornima,

     Our HW connection as below.(D8~D15 8-bit, Input ID 3, style1)

 reg0x3b=0xd4 maybe is wrong, we also tried to remove reg0x3b setting, the result is same, no signal output.

And, it's still no signal output when we tried the 720p50 script  as below.

1. Does any other register setting we need to consider or check?

2. Can adv7513 output test pattern to HDMI even no signal input via data line?

Thanks & Best Regards!

Hi,

 Could you please crosscheck your schematic under 6318.ADV7511W_Eval_Sch_revA.pdf

 Please let us know your Rx ? ADV7513 is HDMI transmitter and it does not have test pattern generator.But HDMI Receivers ADV7611/ADV7619/ ADV7612 with ADV7511 HDMI transmitter will produce default color output in free Run mode.

Thanks,

Poornima

Hi Poornima

Our Rx is TI DS90UB934. We can measured the signals of Hsync, Vsync, PCLK, Data on ADV7513 side.

       Hsync Freq is almost 25kHz,

       Vsync Freq is 30Hz, 

       PCLK Freq is almost 96MHz,       

Thanks & Best Regards!

Hi,

Please note that we have verified on the EVAL-ADV7612-7511 evaluation board for the formats 1280x720p30Hz[VIC:62], 1280x720p @30Hz[VIC:67], 1680x720p @30Hz[VIC:81] with YCbCr 4:2:2 8 bit and they all passed. 

It seems like there would be an schematic misconnection between the hardware.

Thanks,

Poornima

Hi, Poornima

We will check hardware connection again. Thank you very much.

Thanks & Best Regards

Hi,

 Make sure the connection between TI DS90UB934 and HSync/VSync/DE Pins.

Thanks,

Poornima
