Microchip OS81110 MOST智能网络接口控制方案

Microchip公司的OS81110是用于车内网络接口标准(MOST)的智能网络接口控制器,数据速率150Mbps,其智能网络接口控制器(INIC)架构能从现在的MOST无缝地升级到MOST150, 也能用于MOST25和MOST50的应用.工作电压1.8 V/3.3 V.本文介绍了OS81110主要特性和硬件框图, MOST150视频演示框图, OS81110 cPHY评估板主要特性和框图与应用框图,电路图,PCB元件布局图和PCB顶层与底层走线图.

The OS81110 is a new Network Interface Controller that supports MOST (Media Oriented Systems Transport) data transport at 150 Mbits/s. The chip has been architected to enable a seamless migration of existing MOST applications and systems to MOST150. It uses SMSC’s familiar Intelligent Network Interface Controller (INIC) architecture, also used for MOST25 and MOST50 applications. It fully encapsulates the network interface functions and can also operate as a stand-alone solution. The OS81110 uses the same INIC API for the legacy features, which allows existing application software including the NetServices driver stack to be migrated to MOST150 with minimal required changes.
