3 Description

The HD3SS460 is a high-speed bi-directional passive

switch in mux or demux configurations. Based on

control pin POL the device provides switching to

accommodate connector flipping. The device also

provides muxing between 2Ch Data / 2Ch Video and

all 4Ch Video based on control pin AMSEL.

The device also provides cross points MUX for low

speed pins as needed in flippable connector

implementation.

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 0-2V and has

differential signaling with differential amplitude up to

1800mVpp. 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. It

consumes <2 mW of power when operational and

<5μW in shutdown mode, exercisable by EN pin.
