[原创] TI USB Type－C和供电迷你坞站参考设计TIDA－01243

TI公司的USB Type-C和供电迷你坞站提供了包括音频,USB数据,供电和视频在内的完整解决方案,尺寸只有2吋x4吋,支持USB Type-C PD端口的电流源和沉功能,视频输出包括显示器端口(DisplayPort)和HDMI,主要用在笔记本电脑.本文介绍了迷你坞站所采用元件之一高速双向无源开关HD3SS460主要特性和功能框图,以及评估板USB Type-C™ Mini Dock EVM主要特性,框图,电路图,材料清单和PCB设计图.

The HD3SS460 is a high-speed bi-directional passiveswitch in mux or demux configurations. Based oncontrol pin POL the device provides switching toaccommodate connector flipping. The device alsoprovides muxing between 2Ch Data/2Ch Video and all 4Ch Video based on control pin AMSEL.

The device also provides cross points MUX for lowspeed pins as needed in　flippable connectorimplementation.

The HD3SS460 is a generic analog differentialpassive switch that can work for any high speedinterface applications as long as it is biased at acommon mode voltage range of 0-2V and hasdifferential signaling with differential amplitude up to1800mVpp. It employs an adaptive tracking thatensures the channel remains unchanged for entirecommon mode voltage range.
