I have been using the EVAL-SPoE-KIT-AZ to test media conversion with SPoE.
I noticed on the LTC9111 Board there is an MCU installed. The circuit diagram says it's "Eval Purpose Components Only". However when I desoldered the MCU the media conversion no longer worked.
Looking into the circuit and datasheet of the ADIN1100 there are strapping options for using the PHY as a media converter without an MCU. Regarding the ADIN1200 it doesn't look like it works without the MCU.
Changing the resistors so it disables software power down mode gives me a feedback from the link LEDs but I cannot ping any device through the converter.
Is there something I am missing or is it not possible to assemble a media converter without using an MCU?
Thanks for your feedback.
