Hello,

My customer has a question about DS90UB914A. 

As for 0x26 (0x46 in their case since they used RX channel 1), why resister needs to be changed to 45.3 Ohm?

I am awaiting your reply.

Thanks ,

Masayuki Uchihara

    Hello,

    This register was included in Oct 2016 revision of datasheet as it had been found beneficial for specific customer use case to alleviate PCB design issues. Typically this would be used in conjunction with register 0x27.
    For a non-standard use case it is recommended to perform valildation at the system level when changing these registers.

    Regards,
