USB traces are matched to 90 ohms differential / 30 ohms single ended. The circuit is a 50 ohms impedance controlled design. It does not translate or distort data packets like a hub but does reproduce and reclock the original data by 100%. It receives and transmits USB data using a dedicated ULPI-transceiver, buffers and translates by our proprietary logic using FPGA technology and isolates using industry-leading RF-type isolators by Silicon Labs with least possible capacitance. The 7054-based USB Hi-Speed Isolator is a phy-level receiver/isolator/reclocker/repacketizer working at a bidirectional bandwidth of 480 MBit/s. nearly all customers seem to hear a difference in audiophile-grade environments in favour of the Industrial one.Industrial version has full characterized parts and some better parts in sense of temperature grade (this is the reason for the name given).quality audio measurements confirm this.both versions do the same job: isolate, repacketize, provide clean power.We really cannot comment in a scientific way on the difference of Industrial vs Standard version in terms of audio quality. I heard the Industrial version is vastly superior sounding to the Standard version. Thanks to our fully equipped audio lab, we had the chance to take special attention keeping the noise of the power supply output as low as possible in the 20Hz-20kHz range and we also optimized current flow using a high-speed current sensor probe that resulted in the probably industrial-wide lowest packet noise (8 kHz and harmonics).įollowing measurements are showing a typical ground loop issue (first image), cured by galvanic isolation (second image): If you search the web, you will find lots of positive comments and reviews about it. In an audio application, the resulting sound quality improvement is the effect of breaking all the noise coming from the host computer.Īs this is a true industrial product, we focus primarily professional applications like automation systems, medical and research labs.īut of course, as this product is designed for low noise (research labs need this to gain dynamic range from nanovolts to kilovolts) and perfect signal integrity, we understand the demand of audio enthusiasts. The intended purpose is complete isolation of both data and power lines. All applications requiring clean and stable USB connections with separate groundsįAQ Would the Isolator improve the sound quality?.Environments requiring safety insulation.The galvanic isolation barrier withstands potential difference up to 2500V RMS. 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. USB 2.0 Hi-Speed Isolator withstands up to 2.5kV RMS 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. Previous isolators where limited to Full Speed (12 MBit/s) and Low Speed (1.5 MBit/s) transmission. Industrial Version (bottom) with orange colored high retention connectors The Innovation Now available: world’s first in-the-box solution to galvanically isolate the USB 2.0 bus in all speed modes. Intona Review from Intona Review from ĭescription High Speed USB Isolator – INDUSTRIAL VERSION (best for audio) Please read this excellent review from ! don’t just take our word for it, but this Intona is an excellent choice to add to any system! It’s the real deal, and more than just some USB cleaner device. National compliances: FCC, CE, RCM, ICES-003.Impedance controlled high-speed circuit design.Status LED for each port showing bus state and speed.
