EQCO5X31C0-I/6NX

Overview

The EQCO5X31C0-I/6NX is an industrial dual-channel USB 3.2 Gen 1 reclocker and redriver designed to extend SuperSpeed cable distances up to 16 meters. It operates at a data rate of 5 Gbps with a single 1.2V supply, drawing 100 mA during operation. The device features EyeOpen™ technology for automatic cable compensation ranging from 0 to 24 dB in 1 dB steps. It supports both Shielded Twisted Pair (STP) and coaxial cables, functioning without an external reference clock. The component is housed in a 20-pin 4 mm QFN package with wettable flanks and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• EyeOpen™ technology provides automatic adaptive equalization to compensate for cable attenuation.
• MarginLink™ integrated signal integrity testing capability allows for runtime evaluation of link margins.
• Reference-clock-free Clock-Data Recovery (CDR) restores signal timing integrity without external crystals.
• Supports transparent transmission of all USB 3.2 SuperSpeed signaling including LFPS and electrical-idle states.

Applications

• Extended reach for video conference systems
• Extended reach cables for VR gaming applications
• Extending active USB 3.2 cables
• Extending USB3 Vision™ systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package and temperature grade alignment. Confirm that the intended application environment falls within the specified industrial operating limits. Review the latest datasheet revision for any errata or design guideline updates prior to finalizing procurement specifications.

Selection Notes

Select this component when extending USB 3.2 SuperSpeed links beyond standard lengths while maintaining signal integrity. Ensure the design accommodates the required 1.2V power supply and decoupling strategy. Consider the supported cable types, such as STP or coax, and verify that the total insertion loss remains within the device's compensation capabilities.
