High Speed USB Isolator

Now available: world's first in-the-box solution to galvanically isolate the USB 2.0 bus in all speed modes.
Low Speed, Full Speed and High Speed.

The Innovation

Previous isolators where limited to Full Speed (12 MBit/s) and Low Speed (1.5 MBit/s) transmission. This new product is capable of transmitting USB Hi-Speed (480 MBit/s) while providing full galvanic isolation of both the data and the power lines.

USB 2.0 Hi-Speed Isolator withstands up to 2.5kVRMS

This product is an ideal solution to break ground loops, avoid noise coupling and protect ports from power surges and voltage spikes in applications which require high speed USB transfers. The galvanic isolation barrier withstands potential difference up to 2500VRMS.
