About the PHY Module The physical layer is at the bottom layer of OSI. The Physical Layer Protocol defines electrical signals, line states, clock requirements, data encoding, and connectors for data transmission. The device of the physical layer is called the phy. The gray block diagram in the figure shows the internal module diagram of the PHY chip. Mac devices exchange data with PHY through the MII interface. We can see some work done by PHY when

Q: How to implement a Single-Chip Ethernet microcontroller? A: The trick is to integrate the microcontroller, Ethernet Media Access Controller (MAC), and physical interface transceiver (PHY) into the same chip, which can remove many external components. This solution enables good matching between MAC and PHY, and reduces the number of pins and chip area. The Single-Chip Ethernet microcontroller also reduces power consumption, especially when the power loss mode is used. Q: What is an Ethernet MA

Article Title: how to adjust the Nic working mode in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Currently, NICs are generally in 10/100 M adaptive working mode. when configuring Nic parameters, we seldom consider the working mode, however, on key devices with large traffic volumes such as routers, switches, and proxy servers, we should specify the

, this will cause failure of other devices. ARP monitoring should not be used together with miimon. Setting 0 disables ARP monitoring. The default value is 0. Miimon Specifies the MII link monitoring frequency in milliseconds (MS ). This will determine the frequency at which the driver checks the status of each slave link. 0 indicates that MII link monitoring is disabled. 100 can be used as a go

considerations2.4.2 Mii InterfaceW3100A supports two MII types. One is serial Mii, the other is half-bit Mii, but w3150a+ only supports half-bit Mii. Therefore, if you are currently using Serial Mii mode, you will need to adjust

According to The Datasheet of ip101a, the number of chips in the 9,10, 12,13, and 15 is phyad0 ~ Phyad4. (In fact, phyad and led share pins ). This phyad is configurable, and there are two ways to determine the PHY address. (1) Hardware Determined by the latch level after the chip is powered on or reset. For example, the 9-foot high level "1", and the rest is low level 0, phyadr [4-0] = 0x01 (bit: 00001) (2) using software Because phyad has five digits, that is, the range of the PHY address is 0

interface circuit should be indispensable, but it is also relatively complicated. The Ethernet interface circuit consists of the Mac controller and the physical layer interface (physical layer, phy. The lpc2368 is embedded with an Ethernet controller that supports streamlined media independent interfaces (rmii) and buffered DMA interfaces (BDI ), ethernet Access of 10 Mbit/s/Mbit/s is available in half duplex and full duplex modes. Therefore, the lpc2368 actually includes Ethernet MAC control

transmission media, and electrical equality are different. The following describes the most commonly used Ethernet NIC. Ethernet adopts CSMA/CD (carrier-based multi-channel access/conflict detection) control technology. He mainly defines how the physical layer and data link layer work. The data link layer and the physical layer implement their own functions, so they do not care about how the other party operates. There are standard interfaces (such as MII
