[64D7274] This chip contains the output drivers and some "corporate

You can see the LM3045 chips in the schematics for the TROPIC design - which seems to be a straight copy (licensed from IBM by National Semiconductor) of the 'Pinegrove'-based adapters: https://www.ardent-tool.com/datasheets/NS_AN-816.pdf
