Toshiba has recently launched “TDS4A212MX” and “TDS4B212MX,” multiplexer/demultiplexer (Mux/De-Mux) switches for high-speed differential signals such as PCIe 5.0, USB4 and USB4 Ver.2, for PCs, server equipment, mobile devices and similar applications. The new products can be used as a 2-input 1-output Mux switch and a 1-input 2-output De-Mux switch.
The new products use Toshiba's proprietary SOI process (TarfSOI) to achieve very high bandwidths, an industry-leading -3 dB bandwidth (differential) of 27.5 GHz (typical) for TDS4B212MX, and 26.2 GHz (typical) for TDS4A212MX. This allows the new products to be used as a Mux/De-Mux switch for high-speed differential signals such as PCIe 5.0, USB4, and USB4 Ver.2.
TDS4B212MX and TDS4A212MX have different pin assignments. That TDS4B212MX is optimized for high-frequency characteristics. TDS4A212MX has a pin assignment that considers circuit board layout.
