I am working on ADV7393 encoder. It is interfaced to TI's TDA2Px processor.16 data lines from SoC is connected to the ADV7393 along with Clk,Hsync,Vsync. The output of DAC1 of ADV7393 is connected to ADA4430.
We are getting an image on the display. But the image is duplicated.
We are using the following settings.
Can anyone suggest what can be the reason for this duplicated data output.
Is there an issue from the processor side or the settings from ADV7393?
CVBS imply interlaced video. When displaying interlace video on a progressive sink, you will get a double image.
Please try with different sink.
Thanks for your quick reply. Should I try with interlaced sink?
This is how the connection is. 16 data lines from the processor is connected to the ADV7393.
Can the output of DAC1 be RGB? Currently it is CVBS out.
ADV739x can support Multiformat video output,
Composite (CVBS) and S-Video (Y-C),Component YPrPb (SD, ED, and HD)and Component RGB (SD, ED, and HD).

With your suggestion I tried with Table 78 (16-Bit 525i RGB In, RGB Out) As below, still I am getting the output as above.
Can you please suggest
