HUI-01 adopts the latest USB ground loop isolation design to solve the interference problem caused by ground loops in USB transmission lines when electronic devices are connected to each other. Ground loop interference is caused when two electronic devices share a ground wire. This shared ground wire will cause current loops, causing signal interference and affecting data transmission quality. Use a ground loop isolator to isolate the grounds of two connected electronic devices.
Prevent the occurrence of ground loop interference and solve the problem of signal interference caused by current loops caused by shared ground wires.
In order to solve this problem, we designed the HUI-01 USB ground loop isolator. This isolator has two input interfaces on the input side. A switch selects the signal input from TYPE-C or TYPA-B. The output side is a TYPE-A interface and a TYPE-C external power supply input interface. The external power supply input interface has a rated voltage of 5 volts and does not need to be plugged in under normal use. Apple mobile devices limit the output current of their interfaces. So when using an Apple mobile device to connect to the D/A converter and requiring larger current, The external power supply input interface can provide 5 volt DC and abundant current. Allow the connected device to operate smoothly and normally.
1. The input and output sides support ±15kV (air discharge) and ±8kV (contact discharge).
2. Support USB 2.0 Low-Speed / Full-Speed and High-Speed mode.
3. Supports retiming to minimize jitter and skew in the USB output signal.
4. Use a low phase noise / low jitter clock to the isolation chip for best results
5. Use ultra low noise regulator for isolation chip for best results.
6. The output side supports external 5V power supply input.
