沁恒USB2.0高速通讯+USB2.0百兆网卡拓展+USB PD快充三合一方案简介
方案概述
Type-C接口支持充电、USB通信、DP显示等功能,顺应笔记本轻便化设计趋势而广泛应用,当带有Type-C端口的主机需要外接键盘、鼠标、U盘等外设时,需要通过HUB扩展多路USB端口;需要外接网线时,需要通过USB网卡芯片扩展以太网接口。长时间联网状态下移动设备受电量限制还需同时支持充电功能。
Type-C PD快充+HUB+网卡方案实现USB2.0高速端口扩展与百兆以太网接口拓展,支持Type-C PD充电。该方案主要包含工业级USB2.0高速4端口HUB CH334、USB网卡芯片CH397和PD芯片CH227,外围精简。USB2.0高速通讯+USB2.0百兆网卡拓展+USB PD快充三合一。
