Toshiba Electronics Europe GmbH (Toshiba) has launched two new switches, the TDS4A212MX 2:1 multiplexer and TDS4B212MX 1:2 demultiplexer, designed for up to 32 Gbps high-speed differential signaling. Housed in a compact package, the devices support PCIe® 5.0, USB4® Ver.2, Thunderbolt™ 4 and DisplayPort™ 2.0 to connect and expand peripheral devices in applications such as PCs, server equipment, mobile devices and more.

The two new products offer a -3 dB bandwidth (differential) of 26.2 GHz or 27.5 GHz (typ.) at a maximum DC current in active mode of 150 µA, ensuring high signal integrity levels. Toshiba achieves these high-performance characteristics by adopting the company’s original silicon-on-insulator complementary metal oxide semiconductor front-end process technology, called TaRFSOI™.

The differential signal operating range is 0 to 2.0 V for common mode voltage and a 0 to 1.8 Vpp for differential voltage swing, supporting a wide range of differential interface standards. In standby mode, the current consumption can be reduced to 10 µA and below to conserve power consumption. The new devices can operate in ambient temperatures from -40ºC to +85ºC.

Housed in a tiny XQFN16 2.4 mm x 1.6 mm package with a 0.4 mm profile, the two devices address the needs of engineers looking for PCB real-estate miniaturization. The TDS4B212MX has an optimized pinout to achieve high-frequency performance, while the TDS4A212MX’s pinout eases circuit board layout.

In addition to these two new high-performance devices for USB4®, PCIe® Gen 4 and Thunderbolt™ 4, Toshiba has also increased the range available from Farnell for other high-speed bus switches. These would be suitable for USB® 2.0, PCIe® Gen1, also general purpose Input/Output  in 5 V and low voltage along with level shifting devices for I²C type interfaces. This gives design engineers a wide selection of bus switch and level shift options.
