EQCO5X31C0-I/6NX is an industrial-grade dual-channel single-lane USB3.2 Gen1 (5Gbps) reclocking redriver from Microchip, integrating adaptive equalizer, crystal-less CDR (Clock Data Recovery) and bidirectional signal driver in a single IC. Natively supporting STP shielded twisted pair and coaxial cables, it adopts proprietary EyeOpen™ adaptive cable compensation and MarginLink™ link integrity test technology. It extends standard USB3.2 transmission distance from 1m up to 5m (for cables mixed with USB2.0 signaling), and maximum 16m for pure USB3.2-only links. Housed in compact 4×4mm 20-VQFN wettable flank SMD package, it operates on single 1.2V low supply voltage with industrial temperature range -40℃ ~ +85℃. No external crystal required, on-chip integrated terminations minimize BOM count. Fully transparent to all USB3.2 SuperSpeed signaling including LFPS and electrical idle. Target applications include industrial USB3 Vision cameras, VR video equipment, long active USB cables and video conference systems, solving signal attenuation, accumulated jitter and closed eye diagram caused by long cables or PCB traces. Suffix Definition: EQCO5X31 = 5Gbps industrial USB3.2 reclocker redriver; C0 = silicon revision; I = Industrial temperature grade (-40~+85℃); 6NX = Tray packaging, lead-free compliant.

1. Crystal-less integrated CDR reclocker to block jitter accumulation Bidirectional clock-data recovery without external reference oscillator regenerates clean timing from distorted signals. Unlike linear-only redrivers, it eliminates cumulative long-cable jitter to meet USB electrical specs for up to 16m links. 2. EyeOpen™ fully automatic adaptive equalization with 0~24dB range Receiver continuously measures cable high-frequency loss and auto-adjusts EQ gain in 1dB fine steps, compatible with various cable lengths & materials without hardware jumper setup. 3. MarginLink™ real-time link quality diagnostic On-chip signal integrity test function allows host to read link margin dynamically for predictive maintenance of aging cables or poor contact in industrial systems. 4. Integrated on-chip signal terminations to reduce BOM cost Built-in differential matching resistors on TX/RX ports remove external precision passive components, simplifying PCB layout and cutting assembly expense. 5. Dual long-reach operation modes for flexible deployment Supports universal 5m cables mixed with USB2.0 signals, and dedicated 16m pure USB3.2 high-speed links, ideal for industrial vision long-distance host-camera wiring. 6. Single 1.2V low-voltage supply with low-power sleep mode Single-core 1.2V power rail; automatic deep sleep mode cuts power when no high-speed traffic, optimized for battery-powered portable vision hardware. 7. Tiny 4×4mm VQFN compact footprint for space-constrained designs 20-pin small SMD package with wettable flanks ensures high reflow soldering yield, perfect for miniature camera modules and compact active USB extender PCBs. 8. Fully transparent USB protocol forwarding, zero firmware required Transparent to USB host & device without packet modification or interception, compatible with all USB3.2 peripherals (industrial cameras, storage, VR gear) with no custom driver development.
