8.1 Overview
The HD3SS460 is a high-speed bi-directional passive 4-6 cross-point switch in mux or demux configurations.
Based on control pin POL the device provides switching to accommodate USB Type-C plug flipping. The device
provides multiple signal switching options that allow system implementation flexibility.
The HD3SS460 is a generic analog, differential passive switch that can work for any high speed interface
applications as long as it is biased at a common mode voltage range of 0-2 V and has differential signaling with
differential amplitude up to 1800 mVpp. It employs an adaptive tracking that ensures the channel remains
unchanged for entire common mode voltage range
Excellent dynamic characteristics of the device allow high speed switching with minimum attenuation to the
signal eye diagram with very little added jitter.
