Hi,

For the RST pin, it is mentioned that it is critical to reset the PHY after VCC. In our prototype, we have pulled the RSTN high using VCC, and currently, it is working fine. Is there a specific need to modify it according to the datasheet, or is this fine?

Hello,

You should modify according to the datasheet to guarantee proper performance and to reset the digital logic of the DPHY440 after the VCC supply is stable (that is, the power supply has reached the minimum recommended operating voltage).

Thanks,

Zach
