Mux/demux ICs switch high-speed signals

Two multiplexer/demultiplexer switches from Toshiba handle high-speed differential signals, such as PCIe 5.0, USB4, and USB4 V.2. The TDS4A212MX and TDS4B212MX, which have different pin assignments, can be used as a 2-input, 1-output multiplexer and a 1-input, 2-output demultiplexer in PCs, server equipment, and mobile devices.

Both of these devices are manufactured on Toshiba’s silicon-on-insulator process to achieve high bandwidth. The TDS4A212MX has a -3-dB bandwidth of 26.2 GHz typical, while the TDS4B212MX achieves a higher -3-dB bandwidth of 27.5 GHz typical. Optimized pin assignments enhance the high-frequency characteristics of the TDS4B212MX. In contrast, the pin assignment for the TDS4A212MX is designed with circuit board layout considerations in mind.

Main specifications for these switches include:
