    We were not properly managing tx_datain_valid signal for triple rate.

    The easyest way to do it is to drive tx_dataout_valid directly to that imput.

    Now we can switch between standarts perfectly.

    Thanks for your support

Hi RD-FD,

Good day.

I wish to follow up with you on this case.

We have not heard from you for quite some time.

Do you still have further inquiries on this issue?

If there is no further inquiries, I will transition this thread to community support.


Thank you.

Best Regards,

HI ZulsyafiqH_Intel,

Thanks for your response.

We just changed from single rate to triple rate as you adviced us, but we are still not having image when switch to HD-SDI.

Previously we implemented succesfully HD-SDI and 3G-SDI versions of the IP as transmitter sepparately. But so far we have not been able to use both standards using the same IP core.

Is there any important consideration that we may be missing?
