The new products use Toshiba's proprietary SOI process (TarfSOI™) to achieve very high bandwidths: an industry-leading[1] -3-dB bandwidth (differential) of 27.5GHz(typ.) for TDS4B212MX, and 26.2GHz(typ.) for TDS4A212MX. This allows the new products to be used as a Mux/De-Mux switch for high-speed differential signals such as PCIe® 5.0, USB4® and USB4® Ver.2.
TDS4B212MX and TDS4A212MX have different pin assignments. That of TDS4B212MX is optimized for high-frequency characteristics. TDS4A212MX has a pin assignment that considers circuit board layout.
