The TMUXHS4412 is a high-speed bidirectional passive switch which can be used for both multiplexer (mux) and demultiplexer (demux) configurations. The TMUXHS4412 is a analog differential passive mux or demux that works for many high-speed differential interfaces for data rates up to 20 Gbps including PCI Express 4.0. The device can be used for higher data rates where electrical channel has signal integrity margins. The TMUXHS4412 supports differential signaling with common mode voltage range (CMV) of up to 0 to 1.8 V and with differential amplitude up to 1800 mVpp. Adaptive CMV tracking ensures the channel through the device remains unchanged for the entire common mode voltage range.

The excellent dynamic characteristics of the TMUXHS4412 result minimum attenuation to the signal eye diagram with very little added jitter. The device’s silicon design is optimized for excellent frequency response at higher frequency spectrum of the signals. Its silicon signal traces and switch network are matched for best intra-pair skew performance.

The TMUXHS4412 has an extended industrial temperature range that suits many rugged applications including industrial and high reliability use cases.
