Other Parts Discussed in Thread: DS90UB936-Q1

ALL HI!

I currently have an application. I don't know whether it is feasible to use ds90ub935-q1 and ds90ub936-q1. Please check it. thank you!As shown in the figure below！

The SOC board is equipped with Mipi interface and needs to be remotely connected with MCU board and LCD screen, with a distance of about 10m.SOC provides Mipi data interface and screen reset signal. Screen backlight adjusts PWM signal to LCD screen. SOC communicates with MCU through IIC, and SOC controls MCU for interface expansion.Can ds90ub935-q1 and ds90ub936-q1 realize the operation on the diagram?thank you！

Hello Sheng,

yes, this design is a valid use case.

thank you!Hamzeh Jaradat !

If I use twisted pair and operate according to the above scheme, how many meters can I use twisted pair at most?In addition, for long-distance Mipi signal transmission, what special designs should be made for EMC.Can the PCB design of ds90ub935 and ds90ub936 provide PCB source file reference？

I can't find the source file of PCB and can't refer to how to layout and route.

Hello Sheng,

The supported length depends on your transmission channel, i.e. boards design, connectors and cable quality. Typically it should be around 10 meters.

I can provide you with our EVM PCB design files, but our EVMs are not designed to get the best EMC performance, they are designed to demonstrate the functionality.
