DS90UB933-Q1: Where should I test the PoC supply noise

Part Number: DS90UB933-Q1

Hi

I would like to ask that where should I test the PoC supply noise? In datasheet it said to test between DOUT+ and DOUT-, should I need to test the PoC supply noise after the decouple capacitor or just test the noise on the DOUT+ and DOUT- pin directly? Thank you!

    Hello,

    The spec is for the actual DOUT+ and DOUT- signal, therefore I would recommend testing right at the pin if possible.  With that said I would also make sure the imager is running and the PoC network is loaded to get the best representation of the actual operation.

    Regards,
