Toshiba Releases 2:1 Multiplexer / 1:2 Demultiplexer Switches Supporting High-Speed Differential Signals such as PCIe 6.0 and USB4.2.0

May 7, 2026 – Toshiba Electronic Devices & Storage Corporation ("Toshiba") today announced the launch of two 2:1 multiplexer (Mux) / 1:2 demultiplexer (De Mux) switches, the "TDS5C212MX" and "TDS5B212MX", supporting next-generation high-speed interfaces such as PCIe 6.0 and USB4.2.0. Mass shipments of the new products begin today.

As servers, industrial test equipment, robots, and personal computers continue to evolve, the need for reliable switching of ultra-high-speed, wide-bandwidth differential signals within increasingly constrained board space is growing. Toshiba's new products leverage the company's proprietary SOI process (TarfsOI™) to achieve industry-leading differential -3dB bandwidth: 34 GHz (typical) for the TDS5C212MX and 29 GHz (typical) for the TDS5B212MX. The wideband characteristics significantly suppress signal waveform distortion, improving the reliability of high-speed data transmission.

These devices can be used as 2-input/1-output multiplexer switches or 1-input/2-output demultiplexer switches in high-speed differential signal applications such as PCIe 6.0 and USB4.2.0. They support sharing a single high-speed interface among multiple devices and can switch signal paths according to system requirements.

Both products feature a pin layout optimized for high-frequency characteristics. In particular, the TDS5C212MX reduces reflection and loss by shortening the signal path length, thereby enhancing high-speed signal integrity. Both devices support an operating temperature range of -40°C to 125°C, making them suitable for industrial applications.

Toshiba will continue to develop high-performance, high-reliability analog switches that support the evolution of high-speed interfaces, contributing to the development of next-generation systems.
