I have seen the abbreviation PHY beeing used for a handful of different things within the context of Ethernet: a PHY is a type of Ethernet physical layer (eg. 100BASE-TX, 10BASE-T) a PHY is an Eth...
PHY and MAC or even PHY, MAC and switch engine are quite commonly integrated on one chip but PHY, MAC and main system processor rarely are. The embedded world seems to preffer to put the MAC with the processor while the PC world seems to preffer to put the MAC with the PHY.

what is the difference between PHY and MAC chip Ask Question Asked 12 years, 9 months ago Modified 12 years, 9 months ago
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.
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...
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.
In USB, what is the difference between a PHY and a transceiver?
