- 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?

- 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
- 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
- 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
- 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
- Connecting a PHY to another PHY on a same board
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 the Bob-Smith termination? Or can I just have center tap capacitors on both sides like below? Both PHYs share same GND but are powered by different rails
- Difference between USB and ULPI - Electrical Engineering Stack Exchange
What is the difference between USB and ULPI? I know they are closely related, but how they are related is not clear to me First time I came to know when I was looking at this board (See at the bot
