TI公司的DP83826是低延迟低功耗10/100 Mbps工业以太网PHY,支持0BASE-Te, 100BASE-TX以太网协议,满足实时工业以太网系统最严格的要求.TX等待为40ns,RX等待为170ns,电源周期的确定性延迟小于±2ns,固定相XI到TX_CLK关系小于±2 ns,集成的集成电路加强了EMC性能:IEC 61000-4-2 ESD: ±8 kV接触,±15 kV空气;IEC 61000-4-4 EFT:±4 kV @ 5 kHz, 100 kHz;CISPR 22传导发射B类;CISPR 22 辐射发送B类.快速链接删除小于10 μs,电缆长度大于150米.单电源3.3V工作,I/O电压1.8V或3.3V,DP83826E工作温度–40℃到105℃ ,DP83826I工作温度–40℃到85°.主要用在工厂自动化,机器人和运动控制,马达驱动,电网基础设备,建筑物自动化和工业以太网现场总线.中电网为您整理如下详细资料,本文介绍了DP83826主要特性,功能框图,应用框图,以及评估板DP83826EVM主要特性,框图,电路图,材料清单和PCB设计图.

DP83826 Deterministic, Low-Latency, Low-Power, 10/100 Mbps, Industrial Ethernet PHY

The DP83826 offers low and deterministic latency,low power and supports 10BASE-Te, 100BASE-TXEthernet protocols to meet stringent requirements inreal-time industrial Ethernet systems. The deviceincludes hardware bootstraps to achieve fast link-uptime, fast link-drop detection modes and dedicatedreference CLKOUT to clock synchronize othermodules on the systems.

The two configurable modes are BASIC standardEthernet mode that uses a common Ethernet pinout,and ENHANCED Ethernet mode which supportsstandard Ethernet mode and multiple industrialEthernet fieldbus applications with the additionalfeatur..
