以太网(Ethernet)最早是由Xerox(施乐)公司创建的局域网组网规范,1980年DEC、Intel和Xeox三家公司联合开发了初版Ethernet规范—DIX 1.0,1982年这三家公司又推出了修改版本DIX 2.0,并将其提交给EEE 802工作组,经IEEEE成员修改并通过后,成为IEEE的正式标准,并编号为IEEE 802.3。虽然Ethernet规范和IEEE 802.3规范并不完全...
Thank you for your interest in NXP Semiconductor products, The guideline to troubleshoot this would be: Make sure you have correctly mapped your FEC MDI signals to the strapped address PHY and that is mapped to the correct ethernet connector. ...
以太网概述 以太网(Ethernet)是当今现有局域网采用的最通用的通信协议标准,该标准定义了在局域网中采用的电缆类型和信号处理方法。以太网凭借其成本低、通信速率高、抗干扰性强等优点被广泛应用在网络远程监控、交换机、工业自动化等对通信速率要求较高的场合。 以太网是一种产生较早,使用相当广泛的局域网。其最初是...

I want to configure 10G PHY via MDIO/MDC but "10G/25G Ethernet Subsystem IP(PG210)" dont have MDIO lines. @nanz mentioned here [link] "If you'd like to configure the 10G PHY through MDIO, optionally GEM MDIO line can be used.". How to do this?...
MDIO (data, clock) signals are connected to Ethernet PHY devices. You can connect one MDIO interface to multiple Ethernet PHYs that have MDIO interfaces. Thanks. I would like mention, the AM335x MDIO and MDC I/O buffers are powered from the VDDSHV5 power domain which must operate at the...
