- 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?
- 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
- microcontroller - Why are Ethernet MAC and PHY separate? - Electrical . . .
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 makes sense to keep it as a separate chip That said, there are some chips targeted for embedded applications that include both Wiznet, for one, has products in
- what is the difference between PHY and MAC chip

- 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
- stm32 - How to implement OTG FS hardware using embedded PHY on . . .
The OTG FS for STM32F105 107 (which does not support OTG HS 4) has an internal PHY 5 and a pull-up resistor; thus, I attempted to use section 3 3 of AN4879 Regarding the figure that is presented below: • The OTG specification requires the use of a capacitor (maximum value 4 7 μF) on VBUS
- Clock synchronization in ethernet PHY - Electrical Engineering Stack . . .
I am beginning to start with ethernet PHY As per my understanding, digital signal will be transmitted and we apply encoding scheme to incorporate clock information into the data signal Can't we j
- 1000Base-KX PHY - Electrical Engineering Stack Exchange
I am having trouble finding an Ethernet PHY that specifically advertises as being compliant with 1000Base-KX (to be sent over a VXP backplane, a single RX pair and a single TX pair) I found a comm
