Microchip's EQCO510 and EQCO5X31 devices offer a robust two-channel solution for sending high-speed data signals up to 15 meters in
both directions
The USB bus (universal serial bus) standard or USB connection is an industry mainstay that is responsible for transferring data between two devices. The increased degree of incorporation of electronic components into automotive, industrial, and consumer applications has driven the need for USB cabling products over a greater distance. With the goal of bringing reliable, long-distance USB solutions to the market, Microchip Technology today announces two new reclocker/redriver devices. The reclocker/redriver devices EQCO510 for automotive and EQCO5X31 for industry They extend the distance with USB up to 15 meters and are compatible with the USB 3.2 Generation 1 SuperSpeed protocol.
EQCO510 and EQCO5X31 are USB reclocker/redriver devices that can send high-speed data signals up to 5 Gbps in both directions. The reclocking function consists of bit-level Clock-Data Recovery (CDR), which is used to restore signal timing and prevent jitter buildup. The redriving function recovers the levels and shape of the signal fed into the next segment, such as a cable or a PCB trace, thus compensating for signal degradation due to cable attenuation.
“Our customers now have the ability to deploy a fast, reliable USB connectivity solution over a long distance of up to 15 meters, which is five times the typical distance of three meters,” said Matthias Kaestner, corporate vice president, Business Unit. Microchip's automotive infotainment systems business. "These devices also offer our customers a complete option that takes up less board space thanks to the integrated clock and small form factor."
These USB devices incorporate EyeOpen cable compensation™ in the receiver in order to automatically adjust for frequency-dependent losses in the cable and to adjust the signal strength between 0 and 24 dB in 1 dB steps. Devices also feature MarginLink signal integrity checking™, which allows to evaluate the execution time of the integrity throughout the entire path of the signal.
The EQCO510 and EQCO5X31 ICs support twisted-shielded and coaxial cables. Among the devices is an integrated glassless CDR that needs to add fewer components and takes up less space on the board.
Both USB devices are supplied in a 20-pin, 4mm QFN package with wettable flanks. The EQCO510 for automotive meets the AEC-Q100 Grade 2 reliability standard and works with temperatures from -40°C to 105°C.
Microchip's USB devices can be used in many automotive applications, such as infotainment systems, data communication modules, and real-time video systems. Its industrial and consumer product applications include machine vision, gaming accessories, and smart cables.
