![]() ![]() It complies with the IEEE-802.3 specifications for 10BaseT (clause 14) and 100BaseTX (clauses 24 and 25).Ĭlick here to download the PDF version of this entire article. ![]() The IEEE-802.3 standard defines the Ethernet PHY. Transfer files through built-in SD/microSD card reader. ![]() The PHY is the physical interface transceiver. Features one Mini DisplayPort, one HDMI port, one VGA port, one USB-C port, three USB 3.0 ports, Gigabit Ethernet port and 3.5mm audio combo jack. With the management interface, upper layers can monitor and control the PHY. The management interface is a two-signal interface-one signal for clocking and the other for data. The MII data interface requires a total of 16 signals. Each channel has its own clock, data, and control signals. The data interface consists of a channel for the transmitter and a separate channel for the receiver. It consists of a data interface and a management interface between a MAC and a PHY (Fig. It is called MII (Media-Independant Interface). And, indeed, there is a standard hardware connection between the MAC and the PHY (usually provided by an external chip). The Media Independent Interface (MII) is an Ethernet industry standard defined in IEEE 802.3. 1 Answer Sorted by: 7 GMAC/EMAC are hardware implementations of the ethernet MAC OSI layer, usually included within SoC chips, as an embedded peripheral. The latest MACs support operation at both 10 Mbits/s and 100 Mbits/s. The Ethernet MAC is defined by the IEEE-802.3 Ethernet standard. It can also lower power consumption, especially if power-down modes are implemented. This enables the MAC and PHY to be matched and reduces the overall pin count and chip footprint. The trick is to incorporate the microcontroller, Ethernet MAC, and PHY on a single chip, thereby eliminating most external components. How do you implement a single-chip Ethernet microcontroller? ![]()
