USB Type C 爆发在即,你足够了解了吗?

USB Type-C已不再是全新话题,这个USB介面协议,与常见用于笔记型电脑的Type-A或Android手机的Micro-B之间最大的差异,在于USB Type-C刘伯温二四六精选料支援正反插的设计。藉由24根脚位左上与右下对称的设计,达到正插与反插都有一半的脚位可正常动作。

Type-C使用率逐渐普及

最简单的USB Type-C介面,支援USB 2.0(表1中的D+与D-),将高速讯号对加入,支援USB 3.1 Gen1(5Gbps)或USB 3.1 Gen2(10Gbps)的传输速度(表1中的Tx+-与Rx+-)。

此外,USB Type-C可透过Power Delivery(以下简称PD)协议,将供电瓦数由原本的5V/3A向上提升至20V/5A。同时,PD 2.0之后的版本加入了Alternative Mode(以下简称Alt-Mode),透过Alt-Mode可重新定义表1的脚位定义,使USB Type-C的接头除了传递资料、电源,还能传递影像资讯。
