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?
