TFP401A-Q1: Cannot output sync signal

Dear Anyiam-san;

I am sorry for late reply.

Because, when you posted reply, the e-mail was not send me.

I will confirm frequency.

Please wait a moment.

Dear Anyiam-san;

I confirmed your requests.

1.Sync signal is HSYNC.

2.Input frequency is 96MHz.

Hi Masaaki-san,

96MHz is not within range of supported frequencies in 2-pixels-per-clock mode. Per your original post, are you sure the issue is with 1-pixel-per clock mode?

Dear Anyiam-san;

I think that you mentioned the ODCK is not within range of specification.

But 96MHz is input clock (HDMI clock).

When in 2-pixlels mode, ODCK is 48MHz.

So, ODCK is within range of specification.

Is this correct?

Hi Masaaki-san,

You are correct, my mistake. I was thinking about a different device with similar function. 

It is strange that you are not getting any sync signals in 1-pixel-per clock mode. Are you still able to see the output ODCK clock and DE signal?

Hi Masaaki-san,

I'm glad to hear you resolved the issue. In HDMI mode, did the HDMI stream contain audio? The TFP401 should work with HDMI inputs, but it will not work correctly if the HDMI stream includes audio.
