TI公司的USB Type-C和供电迷你坞站提供了包罗音频,USB数据,供电和视频在内的完整办理方案,尺寸只有2x4,支持USB Type-C PD端口的电流源和沉功能,视频输出包罗显示器端口(DisplayPort)和HDMI,主要用在条记本电脑.本文先容了迷你坞站所接纳元件之一高速双向无源开关HD3SS460主要特点和功能框架图,以及评估板USB Type-C™ Mini Dock EVM主要特点,框架图,电路图,质料清单和PCB设计原理图.

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.

Excellent dynamic characteristics of the device allowhigh speed switching with minimum attenuation to thesignal eye diagram with very little added jitter. Itconsumes <2 mW of power when operational and<5μW in shutdown mode, exercisable by EN pin.

HD3SS460主要特点:

• Provides MUX Solution for USB Type-CTMEcosystem Including Alternate Mode (AM)
• Provides Wide Channel Selection ChoicesIncluding U
