Boge,
you can refer to our EVM design or d/s application circuit, you can use 1 port or 2 port. this is our chip's function.

Hi Steven,
I read datasheet DS90UB947-Q1 pin DOUT0+/- and DOUT1+/- must be AC-coupled with a 33nF capacitor, and DS90UB940-Q1 pin RIN0+/- and RIN1+/- too. In case i use FR-4 PCB trace connect DS90UB947-Q1 and DS90UB940-Q1,Do I need to use capacitor between 2 IC?. How many capacitor I need?.
Thanks,

Hi Steven,
In order to control mode operation UB947 and UB940, can I use only I2C config?. If not, how to control mode UB947 and UB940?.
Thank you so much.

Bang,
You can configure the working mode through mode_sel0/1 pins (please see the description on mode selection), also you can configure the registers to select the suitable work mode through I2C.

Hi Steven,
In my board, i use FR4 trace betwen DS90UB947-Q1 and DS90UB940-Q1, length about 15mm. I convert dual lane LVDS to CSI-2. So which mode i should use to control DS90UB947 and UB940?.
Thank you so much for your help!
Best regards,
