Hi,
1、Can DS90UB947 support 1024x768 resolutions over a single LVDS(4 LVDS lanes + 1 clock)?
Yes, one lane can support 720P data throughput.
2、Regarding to different resolutions, does it need to have extra setting?
In general, it does NOT need special setting. but once you change the video format, please issue one reset for UB947/ub948.

best regards,
Steven

Bang,.
Pls check the d/s, for single lane application of UB947, the maximum PCLK is 96 MHz. So you should secure the resolution & frame rate is within this value.

best regards,
Steven
