Hi,
I would like to know if DP_PWR -> 3.3V should be coming in the wire to connect to CSV-5300A on the input / source side ? Or is it the external power connected to the DP hub is sufficient ?
In our customized boards DP is not getting extended to two monitors. Hence trying to figure out the issue.

Good day Srikanth,
What graphics chip is used on the source system?
For MST to function the source need to support it, meaning it needs to support DisplayPort 1.2 and the OS should also support MST, like WIN 7 / 8.31 / 10. MAC OS for instance does not support MST.
With regards to power, i am quite sure all DP connections should offer power, but with regards to the MST Hub that gets enough power from the Power Adapter.
Hi,
Thanks for the info. Also I want to know what is the function of config1 and config2 signals in DP ? One DP monitor is working fine even with MST but the second monitor is not working and not getting extended. Can I probe the signals in oscilloscope ? please let us know any hints to resolve this issue.
This sounds like the either the source system does not support MST or the Graphics does not support DIsplayPort 1.2.
The MST Hub should be recognized by the system (or the screen connected to the hub). Then in WIndows Display Settings you can check if the resolution/frequency is correct and choose mirro/extended mode.
Outputs of the MST HUb are DP++ so when converting DP ouput of the MST Hub to HDMI or DVI please use passive adapters, like CAC-1000 / CAC-1001
