  4. Connecting a PHY to another PHY on a same board

    Aug 14, 2022 · Generally, if I'm connecting a PHY to RJ45 connector, I would add center tap capacitors and Bob-Smith termination like below. But if I am connecting a PHY to another PHY, do I still need …

  5. Ethernet switch IC ports in MAC and PHY mode

    Nov 8, 2021 · 1/ for port 2 and 6, the phy is external. Unfortunately though not all phy information is present on an RGMII/GMII and this is sent over MDIO/MDC. The switch needs to know you have a …

  6. In USB, what is the difference between a PHY and a transceiver?

    Mar 26, 2013 · A Phy is similar to a transceiver in that there is usually different signal standards on "both sides of the chip". With Ethernet it is MII/GMII/etc on one side and, well, Ethernet on the other.

  7. Why do Ethernet PHY magnetics have a center tap?
