Hi ,
When we use DS90UH981, the image is offset. Why?
Current environment: pixclock=35M, RGB666, 2 Lane Mipi
The theoretical value of Mipi clock calculated in this way is about 160M.
Mipi clock = Pixclock*RGB666/LANE/2 = 35*18/2/2 ==160M
But why it actually need to provide at least 260M clock to display the picture.
There is also a problem that the displayed picture was offset.
Please provide some help. Thank you very much!

您好,哪里有描述至少260MHz的时钟才能显示?DS90UH981是NDA器件,您这边是否已经申请到完整的数据手册?
不同接口的ADAs产品和IVI产品速率的评估方法是不同的,您参考下这篇应用手册,关于速率评估方法的详细介绍:
