Re: Strange behavior of SSPD of ADV7842

Matt,

 

Getting back to the Software guide description for  CH1_SSPD_DVALID (copied below)...

 

Can you please clarify what goes on with this after a reset? I am seeing that with a valid video source connected this bit is not set to indicate valid until at least 100 milliseconds after a reset.  2^22 x 1/28MHz is about 150 milliseconds, correct?

Am I correct in saying that this bit is held low at reset for ~150 milliseconds regardless of any video source connection?
