Toshiba Electronics Europe has introduced two new high-performance switches, the TDS4A212MX 2:1 multiplexer (Mux) and the TDS4B212MX 1:2 demultiplexer (De-Mux), designed for high-speed differential signaling of up to 32Gbps. These devices are compact and support a range of modern connectivity standards, including PCIe 5.0, USB4 Ver.2, Thunderbolt 4, and DisplayPort 2.0, making them ideal for applications in PCs, server equipment, and mobile devices.
Both switches feature a -3dB bandwidth (differential) of 26.2GHz or 27.5GHz (typical), with a maximum DC current of 150µA in active mode, ensuring high signal integrity. Toshiba’s proprietary silicon-on-insulator complementary metal oxide semiconductor (SOI-CMOS) front-end process technology, named TaRFSOI, enables these advanced performance levels.
The differential signal operating range of these devices is 0 to 2.0V for common-mode voltage and 0 to 1.8Vpp for differential voltage swing, supporting a broad spectrum of differential interface standards. To reduce power consumption, they offer a standby mode that lowers current consumption to 10µA or less. Additionally, the devices are capable of operating in ambient temperatures ranging from -40ºC to +85ºC.
These switches are housed in a compact XQFN16 package (2.4mm x 1.6mm with a 0.4mm profile), catering to engineers seeking PCB real-estate miniaturization. The TDS4B212MX has an optimized pinout for high-frequency performance, while the TDS4A212MX is designed to simplify circuit board layout.
In addition to these new devices for USB4, PCIe Gen 4, and Thunderbolt 4, Toshiba has expanded its offerings through Farnell, including switches for USB 2.0, PCIe Gen1, and general-purpose Input/Output (GPIO), as well as level shifting devices for I²C interfaces, providing engineers with a wide array of design options.
