The TMUXHS4212IRKST is a Texas Instruments high-speed analog switch with -3dB bandwidth of 13 GHz. On-resistance is 8.4 Ohm max. Crosstalk is -27 dB at 10 GHz. The switch fabric is two independent 1:2 or 2:1 channels (DPST/SPDT configurable). Supply voltage is 1.71V to 1.98V or 3V to 3.6V. Temperature range is -40°C to 105°C.
Maximum on-resistance is 8.4 Ohm. That's the Ron across the switch path at rated supply and temperature.
The -3dB bandwidth is 13 GHz, which supports 10 GbE, USB 3.2 Gen 2, PCIe Gen 4, and DisplayPort 1.4 signal rates.
The part accepts a single supply in two ranges: 1.71V to 1.98V (1.8V nominal) or 3V to 3.6V (3.3V nominal). Pick the rail that matches your SERDES core voltage.
Yes. USB 3.0 runs at 5 Gbps; the 13 GHz bandwidth and -27 dB crosstalk at 10 GHz give plenty of margin for the 5 Gbps eye pattern. The 1:2 / 2:1 mux topology suits a USB 3.0 port selector or signal redirection.
