@scanlime What prevents me from connecting a Magjack breakout to FPGA pins if I implement the link layer on FPGA? The Magjack has the >>

@RichFelker@scanlime From what I can gather, the transformers are actually part of the PHY; we're just shit at miniaturing them XD. -
@cr1901@RichFelker@scanlime From a standards perspective, yes (so is e.g. the LED for fiber) -
@cr1901@RichFelker@scanlime But back in reality, reason you need PHY IC is that most IC pins object somewhat mightily to inductive loads -
@oshepherd@RichFelker@scanlime From what I can also gather, output of PHY is differential; output from FPGA isn't (without directives). -
@oshepherd@RichFelker@scanlime So presumably with the correct directives, an FPGA's pins could handle the inductive load/voltages? -
@cr1901@RichFelker@scanlime No. The I/O pads are phyiscally incapable. Not built big/robust enough; maybe not even possible in SI process
