Leading innovation: Intona has invented USB 2.0 Hi-Speed galvanic isolation.

Previous isolators were limited to Full Speed (12 MBit/s) and Low Speed (1.5 MBit/s) transmission. This 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 2,500VRMS. There is no capacitive coupling.


  • Provides galvanic isolation to the USB bus
  • Compliant to USB 2.0 Hi-Speed (480 MBit/s)
  • Backwards compatible to Full Speed and Low Speed
  • Isolation withstands up to 2.5kVRMS
  • Advanced ESD protection (15kV IEC Air-gap Discharge)
  • Works out of the box, no drivers needed
  • Transparent to host and device: wide compatibility to all operating systems, embedded systems and devices
  • Works also with hubs and extenders
  • Supports all USB-specific transfers and modes
  • No additional round-trip latency
  • Powered by USB bus, no separate power supply
  • Ultra-quiet power rail isolation, linear regulation
  • 300mA nominal (500mA max.) output current on isolated side
  • Connectors: host-side USB-B; device-side USB-A
  • Status LED for each port showing bus state and speed
  • Impedance controlled high-speed circuit design
  • National compliances: FCC, CE, RCM, ICES-003
  • IP 54 ABS housing
  • Dimensions: 135 x 90 x 46 mm
  • Engineered and manufactured in Germany
