ON Semiconductor – Multiplexer for USB3.1 supports data rates up to 10Gbits/s


The FUSB340 from ON Semiconductor is a 2:1 data switch for USB3.1 Gen1 and USB3.1 Gen2 systems. It supports both the SuperSpeed 5Gbits/s maximum date rate and the SuperSpeed+ 10Gbits/s data rate.

It is intended for use in mobile devices, and in USB Type-C applications in which a reversible cable requires a switch.

The FUSB340 data switch offers superior performance and supports various high-speed data-transmission protocols, in addition to USB3.1:
• PCI Express, Gen 3
• Serial Advanced Technology Attachment (SATA)
• Fibre Channel
• Display Port 1.3

The power specifications of the FUSB340 make it attractive to designers of battery- powered and other power-constrained end- products. It draws just 12μA in active mode. In shut-down mode, the maximum current is less than 1μA.
