It is a bit different from timing shown in Datasheet Figure 4 as follows, that it has 122 clocks interval before valid RGB pixel data after HSYNC.

Could you please confirm ADV7342/7343 is avaiable for RGB data shown in above ?


In addition, time period of active LO at HSYNC is 8 clock length as shown in above, so please confirm whether it is good at ADV7342/7343 and is there any problem or not.
