For the ARJ45 connector used with the DP83825IRMQR, the reference design uses an 2 channel connector with 2 isolated center taps for the magnetics. I wondered if it is required to keep these taps separate or can I short them? Reason is that my customer have an internal re-use part, which is 4 channel and has all the center connections shorted. They are trying to see if they can possibly use this re-use part or not.
Could you also provide reason for why or why not? Thanks a lot.
