Toshiba introduces two new switches

These compact devices support PCIe 5.0, USB4 Ver.2, Thunderbolt 4, and DisplayPort 2.0, enabling expanded connectivity for peripherals in applications such as PCs, servers, and mobile devices.

Both products provide a -3dB differential bandwidth of 26.2GHz or 27.5GHz (typical), with a maximum active mode DC current of 150µA, ensuring exceptional signal integrity. Toshiba achieves this high performance by employing its proprietary silicon-on-insulator CMOS (SOI-CMOS) front-end process, known as TaRFSOI.

These switches support a differential signal operating range of 0 to 2.0V for common mode voltage and a 0 to 1.8 Vpp for differential voltage swing, making them compatible with a variety of differential interface standards. In standby mode, the current consumption is reduced to 10µA or lower, minimising power usage. The devices are also capable of operating in temperatures ranging from -40ºC to +85ºC.

Both the TDS4A212MX and TDS4B212MX are housed in a compact XQFN16 package, measuring just 2.4mm x 1.6mm with a 0.4mm profile, meeting the needs of engineers seeking to minimise PCB real estate. The TDS4B212MX has an optimised pinout for enhanced high-frequency performance, while the TDS4A212MX features a pinout designed for easier circuit board layout.

In addition to these high-performance solutions for USB4, PCIe Gen 4, and Thunderbolt 4, Toshiba has expanded its range of high-speed bus switches available from Farnell. This range includes options for USB 2.0, PCIe Gen1, general-purpose Input/Output (GPIO) in 5V and low voltage, as well as level shifters for I²C interfaces, providing design engineers with a comprehensive selection of bus switch and level shifting solutions.
