Toshiba releases high-speed 2:1 multiplexer / 1:2 demultiplexer switches for industrial applications

Toshiba Electronics Europe GmbH (“Toshiba”) introduces TDS5B212MX and TDS5C212MX, multiplexer (MUX) / demultiplexer (DEMUX) switches for high-speed differential signals. Suitable for servers, industrial testers, robots, and related applications, the new products support high-speed interfaces such as PCIe^® 6.0  and USB4^® Version 2.0 .

The devices use Toshiba’s proprietary SOI process (TarfSOI™)  to achieve a typical -3dB differential bandwidth of 29GHz for TDS5B212MX and 34GHz for TDS5C212MX. These wide bandwidths suppress signal distortion and enhance reliability in high-speed data transmission. In addition, both products feature optimised pin layouts for enhanced high-frequency performance. In particular, the TDS5C212MX minimises signal path length to reduce reflections and transmission losses, further improving high-speed signal integrity.

The devices can be used as 2-input/1-output Mux switches or 1-input/2-output De-Mux switches supporting data rates of up to 64GT/s for high-speed differential interfaces, including PCIe^® 6.0, USB4^® Version 2.0, CXL™ 3.x, Thunderbolt™ 5, and DisplayPort™ 2.0. Both products are also backward compatible with earlier interface standards. The devices enable flexible sharing of a single high-speed interface among multiple devices and dynamic signal path switching according to system requirements.

Housed in the XQFN16 package (2.4mm ×1.6mm x 0.4mm), the products are suitable for high-density designs such as smartphones and wearables. They also operate over a temperature range from -40°C to +125°C, making them suitable for space-constrained industrial applications.

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