KAWASAKI, Japan — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched “ TDS5C212MX” and “ TDS5B212MX,” 2:1 multiplexer (Mux) / 1:2 demultiplexer (De‑Mux) switches that support next-generation high-speed interfaces such as PCIe® 6.0 [1] and USB4® Version 2.0 [2]. Volume shipments of the new products start today.

As servers, industrial testers, robots, and PCs continue to evolve, demand is growing for reliable switching of ultra‑high‑speed, wide‑bandwidth differential signals—such as PCIe® 6.0 and USB4® Version 2.0—within increasingly limited board space. Toshiba’s new products meet this requirement with a proprietary SOI process (TarfSOI™) [3] that achieves an industry‑leading [4] -3‑dB bandwidth (differential) of 34GHz (typ.) for TDS5C212MX and 29GHz (typ.) for TDS5B212MX. These wide bandwidths significantly suppress signal waveform distortion and help to improve reliability in high-speed data transmission.

The new devices can be used as 2-input/1-output Mux switches or 1-input/2-output De-Mux switches in high-speed differential signal applications, such as PCIe® 6.0 and USB4® Version 2.0. They support sharing of a single high-speed interface among multiple devices and switching signal paths according to system requirements.
Article content
Both products feature pin layouts optimized for high-frequency characteristics. In particular, TDS5C212MX minimizes signal path length to reduce reflections and losses, improving high-speed signal integrity. They both support an operating temperature range of -40°C to 125°C, making them suitable for industrial applications.

Toshiba will continue to contribute to next‑generation systems by developing high‑performance, highly reliable analog switches that support the evolution of high‑speed interfaces.
