3 说明

HD3SS460 是一款高速双向无源开关，可采用复用或解复用两种配置。该器件可通过负载点 (POL) 控制引脚进行切换，从而适应连接器换向。该器件还可通过 AMSEL 控制引脚来实现双通道数据/双通道视频与所有四通道视频的复用。

该器件还针对低速引脚提供了交叉点 MUX，可满足可换向连接器实现的需求。

HD3SS460 是一款通用模拟差分无源开关，适用于所有高速接口 应用， 前提条件是该应用在 0V 至 2V 共模电压范围内发生偏置并且具有幅值高达 1800 mVpp 的差分信令。该器件采用自适应跟踪，可确保信道在整个共模电压范围内保持不变。

该器件具有出色的动态特性，可在信号眼图衰减最小的情况下实现高速转换，并且附加抖动极少。该器件在工作模式下的功耗 < 2mW，关断模式下的功耗 < 5µW（可通过 EN 引脚切换模式）。
