The HD3SS3411-Q1 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-Q1 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 0V to 2V and has differential signaling with differential amplitude up to 1800mVpp. The device offers adaptive tracking that allows users to keep the channel unchanged for the 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. The HD3SS3411-Q1 consumes < 2mW of power when operational and has a shutdown mode exercisable by OEn pin resulting < 2µW.
