I understand PHY to be the physical layer of the transceiver protocol stack. At the same time I understand that transceivers are devices that transmit serial data at a very high speed i.e >100Mbps.
What I am not sure about is ICs that have PHY in their title and others that have Transceiver in their title. Here are 2 examples. One is a USB PHY while the other is USB transceiver.
What is the difference between them?
