Microchip公司的LAN9355是集成了双路MII/RMII/Turbo MII的高性能小占位面积的3端口10/100以太网交换,支持IEEE 1588v2,网络速率高达200Mbps,适合用于消费类电子,嵌入使和工业电子产品.本文介绍了LAN9355主要亮点,框图,电源连接图,评估板EVB-LAN9353主要特性,框图,电路图和材料清单.

Microchip’s LAN9355/LAN9355i is a high-performance, small-footprint, full-featured 3-port managed Ethernet switch. This device is application-optimized for consumer, embedded and Industrial electronic designs which require a highly integrated, cost effective device with switching functionality, flexibility and ease of integration.

Featuring the industry’s smallest form factor 3-port switch, the LAN9355/9355i supports compact PCB design and MII/RMII/Turbo MII (Media Independent, Reduced Media Independent and Turbo Media Independent Interfaces). This device supports Turbo MII mode to accomplish network speeds up to 200 Mbps. The virtual PHY feature mimics a single PHY connection through the MII/RMII/Turbo MII interface to the host SoC, which can reduce software development time. This feature also allows system designers to swap the single PHY and Ethernet switch to create multiple SKUs from the same software driver.
