LAN8871数据手册Microchip中文资料规格书

描述 Description

The Microchip LAN8870/LAN8871/LAN8872 (LAN887x) family of devices provide a compact, cost-effective, single-port 100BASE-T1/1000BASE-T1 Ethernet physical layer transceiver solution compliant with the IEEE 802.3bw-2015 and IEEE 802.3bp-2016 specifications.

The LAN887x provides transmit and receive capability with cable reaches beyond the IEEE 802.3bp standard of up to at least 15 meters for type A and up to at least 40 meters for type B.

The LAN887x is available in both Industrial grade (-40°C to +85°C) and AEC-Q100 Automotive Grade 2 (-40°C to +105°C) temperature ranges and is optimized for applications such as Industrial Automation, IIoT, Automated Driver- Assistance Systems (ADAS), infotainment, telematics, and in-vehicle backbones.

The LAN887x supports communication with an Ethernet MAC via standard RGMII/SGMII interfaces.

The LAN887x is Time Sensitive Networking (TSN) ready, supporting IEEE802.1AS-2020 and IEEE1588-2019 Precision Clock Synchronization Protocol for real time Ethernet networking.

Microchip’s LAN887x EtherGREEN™ energy efficient technology provides low-power 1000BASE-T1/100BASE-T1 PHY operation along with OPEN Alliance TC10 ultra low-power remote sleep and wake-up support.

FlexPWR® variable I/O and core power supply voltages provide flexible design options and further power saving opportunities.

Advanced PHY diagnostics provide the user with troubleshooting capabilities such as cable defect detection of shorts or opens, a receiver Signal Quality Indicator (SQI), over-temperature, under-voltage protection, comprehensive status interrupt support, and various loopback and test modes.



Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects.
