No. 1876	Is transformer needed?	2023-03-09

Dear Sirs, I build circuit where I have multiple Ethernet endpoints and that is why I place RTL8309N on the PCB ( That is second PCB I build with that IC and previous works fine). I wonder if I need to put SM91071AL_E transformer between RTL8309N and CSE-M53G. Both will be on the same PCB with the same ground. See attached piece of schematic. Regards, Chris
