Other Parts Discussed in Thread: TIDM-DELFINO-ETHERCAT, TLK105
On the ref schematic(tidrle9a) of TIDM-DELFINO-ETHERCAT , we can see the PFB pin function(PIN13,15,24) as like below schematic. But I can't find about PFB pin function at datasheet of DP83822. PIN13,15 are NC port and PIN24 is LED-1 at datasheet.
Please let me know function of PFBIN1/2,PFBOUT.
