3 Description

The HD3SS3411 is a high-speed bi-directional passive switch in multiplexer or demultiplexer configurations. Based on control pin SEL, the device provides switching of differential channels between Port B to Port A or Port C to Port A.

The HD3SS3411 is a generic analog differential passive switch that can work for any high speed interface application as long as it is biased at a common mode voltage range of 0 V to 2 V and has differential signaling with differential amplitude up to 1800 mVpp. The device employs 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 little added jitter. It consumes < 2 mW of power when operational and has a shutdown mode exercisable by OEn pin resulting
< 2 µW.
