Professional IDS+VNA+Impedance Controlled USB Cable
Best-in-class signal transfer: Impedance controlled design, double shielding and stronger power lines. Individually characterized.
Our goal was to develop a professional USB 2.0 Hi-Speed cable for highest demands in data and media transmission.
Full compatibility to USB 2.0 specifications and devices are of course the minimum pre-conditions, but we go a huge step further…
For the first time ever, a unique characterized USB cable is available and we are able to classify the performance level of the cable with individually measured data.
The key to highest Signal Integrity
Constant Impedance vs. cable length.
The ideal USB cable shows an absolutely flat impedance vs. cable length. But unfortunately reality is different and all wires in the market show significant impedance variations over length – even in a single production lot.
Where ever there is a change in the impedance, there is a reflection of energy. When these returning energy reflections meet with other imperfections, some of the signal recoils in its original direction and creates multiple echo effects. These echoes reach the receiver at different intervals and make it very hard for the receiver to detect data values on the signal in an error-free way. The effects out of this process can be very similar to those of jitter – the natural, audible enemy in any audiophile HiFi-system. The deformations caused by these echoes can also be cleary seen in the signal eye pattern.
- Highest possible impedance continuity is a key for excellent signal integrity
- Any change in impedance causes a reflection of energy
- The reflected energy causes echo effects which disturb original signal
- The resulting effects are similar to those of Jitter – the natural enemy in any audiophile HiFi-System
- Intona’s Innovation: the first commercial USB 2.0 Hi-Speed cable offering a visible and measured level of impedance continuity
Individual cable characterization by Intona
Before our cables get assembled, we are using our own Vector Network Analyzer to measure and analyze the raw cable. Following the results of the measurement, we are already sorting out parts of the raw cable, which simply don’t meet our internal quality standards for impedance continuity. We are sourcing the raw cable from a german supplier on a very high quality level and of course all parts of the cable are originally fully compliant to USB 2.0 specs but our goal is to build an even better cable.
In other words: we are disposing parts of the raw cable, that other suppliers would love to use!
The remaining part of our raw cable gets carefully assembled, a unique serial number is assigned and the next measurment routine is applied to classify the cable into one of our three quality grades: PREMIUM, REFERENCE and ULTIMATE
One thing is common for all three grades: our internal requirements for impedance continuity are much more demanding and narrower than the original USB 2.0 specifications!
The following charts show a representative Intona cable out of each performance level compared with a Hi-End USB 2.0 audio cable, which has an excellent reputation in the market. Compared with obviously one of the best cables out of this market, each Intona cable is able to show a significant improvement in terms of impedance continuity vs. cable length and thus a dramatically improved reliability and signal integrity.
PREMIUM grade: Intona sets a new standard
- The Premium grade is the Intona standard for a real excellent USB 2.0 Hi-Speed cable
- Impedance vs. cable length is by far more constant compared to one of the most accpeted USB audio cable
- For all applications that require a much better solution than just one off-the-shelve
REFERENCE grade: the upper middle class
- The REFERENCE grade takes it one step further
- Impedance vs. cable length is even more constant compared to our PREMIUM grade
- Better than the vast majority of USB cables in the market, but for us just the “upper middle-class”
- Excellent Signal Integrity for all demanding users
ULTIMATE grade: the best of the best
- The ULTIMATE grade represents Intona’s best cable available
- Only a small percentage of cables achieves this level of quality
- It offers the most constant impedance level vs. cable length
- For ultimate signal integrity and the most reliable data transfer
Intona Double Shielding Technology
The shielding quality of any cable depends on the external conductor’s characteristics, which prevents the exchange of electromagnetic waves between the cable and the external environment.
Electromagnetic Interference (EMI) can seriously disturb and / or disrupt the proper operation of any electrical equipment. In all applications, where a bit-perfect data transfer is one of the top priorities, the best cable shielding is indispensable. Cables can be a main source of transfer for EMI, both as a source and receiver. As a source, the cable can either conduct noise to other equipment or act as an antenna radiating noise. As a receiver, the cable can pick up EMI radiated from other sources.
EMI noise can arise from various sources such as heavy motors, generators, relay controls etc. but even placing signal cables next to power cables can also allow power-line noise to couple onto the signal lines which means a serious disturbance of any data.
Intona‘s USB cable is using a unique shielding technlogy with an additional outer shielding to provide maximum screening attenuation against EMI pollution:
The inner shielding consists of a carefully designed material combination (synthetic/metallic laminate plus braid) which already provides a 100% coverage of the conductors.
The additional unique outer shielding consists of a braided wire with finest filaments made out of tinned copper.
With this shielding technology Intona Technologies has created a USB 2.0 Hi-Speed cert-ready cable, which provides the best possible protection against ESD, RFI and EMI and highest possible signal integrity.
Stronger power lines
In order to provide the most reliable and stable 5V power supply for any external device, we are using stronger power lines compared to other cables.
Premium material selection
For our professional USB cable, we have selected the finest materials available to provide durability and best performance possible.
- Conductors made from Oxygen-Free Copper (OFC) for best conductivity
- 24K gold plated connectors
- Zero-resistance and highly conductive material composition for the plugs
- CNC machined connector housings made from solid all-aluminium
- Intermediate Polyurethane cable sleeve provides ultra-high stability and prevents from buckling
- Outer cover made from ultra fine tinned copper
Engineered and manufactured in Germany.
