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?
