I'm using a TPS23753A to design a PD with no need for data passthrough. The device will be a "dumb" dead end device that just acquires power through PoE.
Reference the schematic snippet below from PMP7298:
My question is this: If I have no need to pass data back out can I eliminate the portion in the red box? I'd like to get rid of T1 (obviously J1 can go away). However the PoE spec mandates that power can come in over either pairs 1&2 and 3&6 or over pairs 4&5 and 7&8. This means I still need to tie pairs 1&2 and 3&6 into the circuit in case power comes in over them. If I don't need the data from them can I just tie 1&2 together over to one side of D3 and tie 3&6 together to the other side of D3? Basically use the same approach that is used with pairs 4&5 and 7&8.
Thanks in advance!
