MICROCONTROLLER - WHY ARE ETHERNET MAC AND PHY SEPARATE?
Dec 16, 2022 I’ve been looking for a MCU/MPU with built-in Ethernet connectivity, and I’ve noticed that most only contain a built-in Ethernet MAC interface and require an external PHY. Why is this the case, as in why do most of these chips not contain both a MAC and a PHY to minimize the number of additional ICs needed? ...

ETHERNET - MAC PHY DEFENITIONS - ELECTRICAL ENGINEERING STACK EXCHANGE
Nov 11, 2015 1. from Wikipedia: The media-independent interface (MII) was originally defined as a standard interface used to connect a Fast Ethernet (i.e., 100 Mbit/s) media access control (MAC) block to a PHY chip. Don't the different Ethernet protocols (GMII, RGMII etc) define PHY <-> PHY connection. ...

WHAT MATTERS WHEN IT COMES TO CHOOSING AN ETHERNET PHY
Feb 11, 2022 Ethernet is an interface specification set forth in IEEE 802.3. One of the elements of IEEE 802.3 is the Ethernet physical (PHY) layer. It is a transceiver component for transmitting and receiving data or Ethernet frames. In the OSI model, Ethernet covers Layer 1 (physical layer) and part of Layer 2 (data link layer). ...
