Toshiba Electronics Europe has introduced two high-speed differential multiplexer/demultiplexer (Mux/De-Mux) switches, the TDS4A212MX and TDS4B212MX, capable of operating at signalling rates of up to 32Gbps. 

These new devices, which come in a compact package, are designed to support standards such as PCIe 5.0, USB4 Ver.2, Thunderbolt 4, and DisplayPort 2.0, facilitating the connection and expansion of peripheral devices in PCs, servers, mobile devices, and more.

Both switches feature a typical -3dB bandwidth (differential) of either 26.2GHz or 27.5GHz and draw a maximum active mode current of 150µA, ensuring a high level of signal integrity. This performance is achieved using Toshiba's proprietary silicon-on-insulator complementary metal-oxide-semiconductor (SOI-CMOS) front-end process technology, known as TaRFSOI.

The switches support differential signal ranges from 0 to 2.0V in common mode voltage and a 0 to 1.8Vpp differential voltage swing, making them compatible with a wide range of differential interface standards. In standby mode, power consumption can be reduced to as low as 10µA, helping to conserve energy. The devices are also rated for operation in ambient temperatures ranging from -40ºC to +85ºC.

Housed in a miniature XQFN16 package measuring 2.4mm x 1.6mm with a profile of 0.4mm, these switches meet the growing demand for PCB space optimisation. The TDS4B212MX offers a pinout optimised for high-frequency performance, while the TDS4A212MX features a pinout designed to simplify circuit board layout.

Alongside these new products, Toshiba has expanded its offering of high-speed bus switches available through Farnell, covering a range of interfaces including USB 2.0, PCIe Gen1, and GPIO in 5V and low voltage applications, as well as level-shifting devices for I²C interfaces. This expanded selection provides engineers with an array of bus switch and level-shift options for their designs.
