ADN8810 RESET and SB


If I will not use SB and RESET pins, how do I connect them? Connect them to ground? PVDD? NIC them?

Moreover the datasheet and some Q&As keep on mentioning that ADN8810 should be used on laser diodes (or diodes in general). I have an experiment that doesn't use diodes but a potentiometer. The circuit will still work yes?
