  1. What does "PHY" refer to? - Electrical Engineering Stack Exchange

    Oct 20, 2021 · a PHY is a type of Ethernet physical layer (eg. 100BASE-TX, 10BASE-T) a PHY is an Ethernet transceiver IC (eg. an IC that converts 100BASE-TX to MII/RMII) a PHY is a physical layer …

  2. what is the difference between PHY and MAC chip

    Jul 11, 2013 · what is the difference between PHY and MAC chip Ask Question Asked 12 years, 6 months ago Modified 12 years, 6 months ago

  3. 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 …

  4. microcontroller - Why are Ethernet MAC and PHY separate? - Electrical ...

    Dec 16, 2022 · The PHY also dissipates a significant amount of power all by itself. And sometimes different media require different PHYs, but the MAC can be the same. For all of these reasons, it …

  5. 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 …

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

    May 23, 2023 · I've a question with the Ethernet PHY connection to the RJ45 connector. With either discrete or integrated magnetics, either with voltage mode PHY or current mode PHY, what is the …

  7. Implementing USB-C PD PHY directly into micro-controller

    Jan 11, 2023 · However, that means extra cost and extra space for the dedicated communication chip. I guess that's ok for most applications, but I'm curious; from reading a presentation explaining the …

  8. The SERDES/transceiver design inside the Ethernet MAC controller

    Nov 15, 2019 · The 1st and 2nd figures are normal application which transmits the data through copper media with coded information (through PCS/PMD/PMA inside the PHY chip). The interface between …

  9. How to define PHY mode and MAC mode between back to back switches

    Oct 13, 2023 · When connecting these devices in back to back mode with RGMII interface between then, I need to define which switch is PHY and which would be MAC right? In that case, can …

  10. MIPI C-PHY Signal Routing - Electrical Engineering Stack Exchange

    Sep 14, 2021 · I've been looking for a good, definitive reference example for MIPI C-PHY signal routing and have come up short. Bear in mind that C-PHY uses a set of 3 signals per lane, with multi-level …
