DS90UB940-Q1: Is there any software driver or refer register configuration about DS90UB940-Q1?

Hello,
There are no drivers required for the 940 deserializer to operate properly. You can use the software tool ALP (Analog Launch Pad www.ti.com/tool/alp) to control the device.

Hi Went,

In most cases, UB940 can run up without any register configuration. So we have no driver to you.

You can be careful of some key registers, such as Back channel register settings, CSI setting, etc.

best regards,

Steven
