Tool/software:
Hi All,
I have a question about the DS25CP114.
Is it okay to input a signal to the LVDS input when VCC is not applied?
I would like to confirm whether the LVDS input has a tolerant function.
The data sheet also says that it is okay to input an LVDS signal even if VCC is not applied, but I wanted to confirm.
Best Regards,

Thank you for your answer.
I have an additional question.
My customer plans to input MIPI D-PHY signals to DS25CP114.
MIPI D-PHY has a voltage difference of 1.2V in LP mode.
I'm sure there will be no problem with the LVDS Input Voltage, but the LVDS Differential Input Voltage exceeds the range.
Is it possible to input MIPI D-PHY signals to DS25CP114?
Best Regards,

This has not been tested, so I am not sure. For MIPI signaling the following switches should suffice. You will need to use two in parallel for the same effect as a Crosspoint switch.
Thank you for your support.
I have an additional question.
For the LVDS Differential Input Voltage (DS25CP114) below, I understand that it is OK if |INp-INn| < Vcc+0.6V. Is my understanding correct?

Hi,
Yes this is correct, but I recommend keeping the swing with 0-1V and follow the DC characteristics for optimal performance:
