Description
The TMUXHS4212 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 many high-speed differential interfaces with data rates up to 16 Gbps. The device can be used for higher data rates where electrical channel has signal integrity margins. The TMUXHS4212 supports differential signaling with common mode voltage range (CMV) of 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 dynamic characteristics of the TMUXHS4212 allows high-speed switching, minimum attenuation to the signal eye diagram, and with very little added jitter. The devices 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 TMUXHS4212 has an extended industrial temperature range that suits many rugged applications including industrial and high reliability use cases.
