Toshiba releases high-speed switches for industrial applications
Toshiba has introduced 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.
