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.
