High-Speed Signals Managed with 32 Gbps Mux/Demux Switches

Housed in a compact package, Toshiba has introduced new switches that support PCIe® 5.0, USB4® Ver.2, Thunderbolt™ 4, and DisplayPort™ 2.0. These switches are designed to connect and expand peripheral devices in various applications, including PCs, server equipment, and mobile devices. The compact design of the switches makes them versatile for a wide range of uses.

The two new products boast a -3 dB bandwidth (differential) of 26.2 GHz or 27.5 GHz (typical) with a maximum DC current in active mode of 150 µA, ensuring high signal integrity levels. Toshiba has achieved these impressive performance characteristics by utilizing its original silicon-on-insulator complementary metal oxide semiconductor (SOI-CMOS) front-end process technology known as TaRFSOI™.

With a differential signal operating range of 0 to 2.0-V for common mode voltage and 0 to 1.8-Vpp for differential voltage swing, the switches support a wide range of differential interface standards. In standby mode, the current consumption can be reduced to 10 µA and below to optimize power efficiency. Moreover, the devices can operate effectively in ambient temperatures ranging from -40ºC to +85ºC.

Encased in a tiny XQFN16 2.4- x 1.6-mm package with a 0.4-mm profile, the two devices cater to engineers seeking PCB real-estate miniaturization. The TDS4B212MX features an optimized pinout for enhanced high-frequency performance, while the TDS4A212MX's pinout simplifies circuit board layout, making them ideal for compact designs.

Aside from these high-performance devices for USB4®, PCIe® Gen 4, and Thunderbolt™ 4, Toshiba has expanded its range available from Farnell to include other high-speed bus switches. These switches are suitable for USB® 2.0, PCIe® Gen1, general-purpose Input/Output (GPIO) in 5V and low voltage, as well as level-shifting devices for I²C type interfaces. This expanded range provides design engineers with a diverse selection of bus switch and level shift options to meet their specific requirements.
