[原创] TI DP83822低功耗单端10／100Mbps以太网PHY解决方案

TI公司的DP83822是低功耗单端10/100Mbps以太网PHY,提供所有在标准双绞线电缆或连接到外部光纤收发器发送和接收数据所有的物理层功能,另外通过标准MII,RMII或RGMII接口连接到MAC,还集成了电缆诊断工具,内置自测试以及容易使用的回送能力,支持多种工业总线,主要用在工业网络和工厂自动化,马达和运动控制,IP网络照相机和建筑物自动化.本文介绍了DP83822主要特性,框图和应用电路,以及评估板DP83822 EVM主要特性,框图,电路图,材料清单和PCB设计图.

The DP83822 is a low power single-port 10/100 Mbps Ethernet PHY. It provides all physical layer functions needed to transmit and receive data over both standard twisted-pair cables or connect to an external fiber optic transceiver. Additionally, the DP83822 provides flexibility to connect to a MAC through a standard MII, RMII, or RGMII interface.

The DP83822 offers integrated cable diagnostic tools, built-in self-test, and loopback capabilities for ease of use. It supports multiple industrial buses with its fast link-down timing as well as Auto-MDIX in forced modes.

The DP83822 offers an innovative and robust approach for reducing power consumption through EEE, WoL and other programmable energy savings modes.

The DP83822 is a feature rich and pin-to-pin upgradeable option for the TLK105, TLK106,TLK105L and TLK106L 10/100 Mbps Ethernet PHYs...
