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.
