Texas Instruments TMUXHS4412 Differential 2:1/1:2 Mux/Demux

Texas Instruments TMUXHS4412 Differential 2:1/1:2 Mux/Demux is a high-speed bidirectional passive switch that can be used for both multiplexer (mux) and demultiplexer (demux) configurations. The TMUXHS4412 is an analog differential passive mux or demux that works for many high-speed differential interfaces for data rates up to 20Gbps, including PCI Express 4.0. The device can be used for higher data rates where the electrical channel has signal integrity margins. The TMUXHS4412 supports differential signaling with a common-mode voltage range (CMV) of up to 0 to 1.8V and with differential amplitude up to 1800mVpp. 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 in minimum attenuation to the signal eye diagram, with very little added jitter. The device’s silicon design is optimized for excellent frequency response at the higher frequency spectrum of the signals. Its silicon signal traces and switch network are matched for best intra-pair skew performance. The Texas Instruments TMUXHS4412 has an extended industrial temperature range that suits many rugged applications, including industrial and high-reliability use cases.
