Toshiba Launches 2:1 Multiplexer/1:2 Demultiplexer Switches That Support High-Speed Differential Signal Such As PCIe 5.0 And USB4

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has 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 more. The new products can be used as a 2-input 1-output Mux switch and a 1-input 2-output De-Mux switch. Shipments start today.

The new products use Toshiba's proprietary SOI process (TarfSOI™) to achieve very high bandwidths: an industry-leading^[1] -3-dB bandwidth (differential) of 27.5GHz(typ.) for TDS4B212MX, and 26.2GHz(typ.) 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 of TDS4B212MX is optimized for high-frequency characteristics. TDS4A212MX has a pin assignment that considers circuit board layout.

Note:
