I'm comfused about transformer. We would like to use PoE RJ45; however, the transformer should be included in RJ45 like attache spec "RJMG301T2XXE3XR.pdf" or we should choose an external transformer? If the answer is transformer should include in RJ45, the choke should should be 1CT : 1CT or have specific requirement?
Another question on PD side, I took a snapshot from PoE vedio, did you have recommand material for bridge diode?
