- What does PHY refer to? - Electrical Engineering Stack Exchange
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 device (more than just the transceiver IC) Is PHY ambiguous and can refer to all of these or did I understand something wrong?
- what is the difference between PHY and MAC chip
A PHY chip or layer converts data between a "clean" clocked digital form which is only suitable for very-short-distance (i e inches) communication, and an analogue form which is suitable for longer range transmission It has no particular clue as to what any of the bits "mean", nor how they should be interpreted or assembled The MAC chip or layer receives bits from the PHY, detects packet
- The SERDES transceiver design inside the Ethernet MAC controller
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 the MAC and PHY is SGMII or XAUI for 1G and 10G base-T Ethernet However, the 3rd figure confuses me
- In USB, what is the difference between a PHY and a transceiver?
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
- ESP32 GPIO [0] number 2 pin is reserved
I am building a custom ESP32 board to send sensor data via firebase But when I try to program the WiFi, I got this error E (111) phy_comm: gpio[0] number: 2 is
- Ethernet switch IC ports in MAC and PHY mode
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 phy connected, and hence that mode It's possible to connect RGMII GMII to another mac also and skip the phy 2 there is no internal phy if it comes out RGMII GMII, and if you are going from mac to mac there will
- fpga - Problems in understanding PCIe blocks in Xilinx Vivado for . . .
These two PHY are actually different, that IP vendor's PHY is below PIPE interface, only contains PCS and PMA, while the PHY in TLP DL PHY also contains PHY-MAC Knowing this difference in different context makes things a bit clear I guess
- How to connect Ethernet Magnetic RJ45
I am connecting up my PHY to an RJ45 with magnetics and was wondering what I do with some pins on it Here is the circuit for the Rj45 w magnetics My questions are: do I connect pin 10 to the ch
