Texas Instruments TMUXHS4212 Differential 2:1 Mux/1:2 Demux

Texas Instruments TMUXHS4212 Differential 2:1 Mux/1:2 Demux is a high-speed bidirectional passive switch in mux or demux configurations. It is suited for many applications, including USB Type-C® and PCI Express. The TMUXHS4212 is a generic analog differential passive mux or demux that works for high-speed differential interfaces with data rates up to 16Gbps. The device can be used for higher data rates where the electrical channel has signal integrity margins. The Texas Instruments TMUXHS4212 2:1/1:2 Differential Mux/Demux supports differential signaling with a common-mode voltage range (CMV) of 0 to 1.8V and differential amplitude up to 1800mVpp. Adaptive CMV tracking ensures the channel through the device remains unchanged for the entire common-mode voltage range.

The TMUXHS4212's dynamic characteristics allow high-speed switching, minimum attenuation to the signal eye diagram, and little added jitter. The device's silicon design is optimized for excellent frequency response at a higher frequency spectrum of the signals. Its silicon signal traces and switch network are matched for excellent intra-pair skew performance. The TMUXHS4212 has an extended industrial temperature range that suits many rugged applications, including industrial and high-reliability use cases.
