Part Number: DS90UB960-Q1
I use DS90UB960 to receive image from AR0231-AP0202-DS90UB913(resolution 1920x1080,20fps). Host processor is TDA2px.
But the DS90UB960 line count register(reg 0x73,0x74 -> 0x437 -> 1079) is one line less than real resolution. Camera real resolution is 1920x1080, I confirm this with logic analyzer.
Here's the register value dump from DS90UB960 and DS90UB913.
So, why? How do I solve this problem?
It sounds like the first video line may be getting discarded due to a FV to LV setup time violation on the 913A side. Please see section 7.4.12 in the 960 datasheet for details on this
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thanks a lot. I set DS90UB960 0x6d bit 3 Forward truncated 1st video line to 1 then solve this problem .
But the image is unstable.Always one line 's data is 0x00.
