Good day!
For one of my projects I need to implement inductorless connection between CH579 and another Ethernet device. So, the questions are:
1) What is the recommended inductorless connection schematic for CH579?
2) How I can disable autonegotiation and force Full-duplex mode on CH579's PHY (as I expect autoneg failure at capacitive connected PHY)?
Answer Back:
1) One of the necessity in using inductive transformer can make various Ethernet device compatible on their voltage level. So there is no stationary inductorless schematic. We can provide some schematic without inductor on the case the PHY are
put on one PCB,attached.
2) On the existing project autonegotiation is not disabled.
Thank you! Yes, the MCU and the other device are sits on the same board. Previously, I did projects with inductor-less connection with good result. But, I used a forced 100FD connection (as Autonegotiation through capacitors often unstable).
Given very sparse documentation for CH579M 10M-only PHY, I wonder how to prevent autonegotiation and force it to operate Duplex mode?
