Re: Arduino ESP32 with KSZ8081 phy
Hi kdgoranale,
thank you for schematics. I'm not sure if I fully understand to it though. However, I'm not HW engineer... Anyway, please check if you connected HR911105A magnetics correctly. CT_TXD and CT_RXD should be connected just to GND via 0.1 uF capacitors. In your schematics, it seems it is connected to voltage rail (ETH_3V3). In addition, I don't understand to a purpose of R44-R47. Could you please explain?
I would recommend you to follow: https://ww1.microchip.com/downloads/en/ ... 02781A.pdf
