EQCO31X20C1-I/8EX

Overview

The EQCO31X20C1-I/8EX is a CoaXPress compliant asymmetric equalizer/driver/repeater from the Microchip Technology EQCO31X20 family. It supports data rates up to 3.125 Gbps over coaxial cables, enabling full-duplex communication with simultaneous power delivery. The device integrates clock-data recovery (CDR), cable drivers, and termination resistors for differential signaling. It operates on a single 1.25V supply within an industrial temperature range (-40°C to +85°C) and is housed in a 16-pin QFN package.

Feature Summary

• Supports CoaXPress standards with asymmetric full-duplex communication capabilities
• Integrates clock-data recovery and cable drivers for signal integrity restoration
• Enables simultaneous high-speed data signaling and power delivery over a single cable
• Operates without external reference clocks or crystals

Applications

• CoaXPress compliant imaging systems
• High-definition camera links
• Connections between frame grabbers and cameras
• Links between FPGAs requiring CoaXPress interface

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm that the specific suffix matches the required package and temperature grade. Check for recent product change notifications regarding manufacturing updates. Ensure compliance with RoHS directives as specified in official documentation.

Selection Notes

Select this component for applications requiring CoaXPress connectivity at speeds up to 3.125 Gbps. Consider the integrated CDR and driver features which reduce external component count. Evaluate the single-supply requirement against system power constraints. Verify compatibility with supported cable types including 75-ohm coax and shielded twisted pair.

Part Context

This part belongs to the EQCO31X20 family of CoaXPress transceivers designed for video and industrial imaging applications. It serves as a bridge between host devices like frame grabbers and peripheral devices such as cameras. The family shares architectural similarities with higher-speed variants but targets lower bandwidth requirements.

Replacement Considerations

Consult Microchip Technology for current recommended replacements if this specific part number is discontinued. Verify pinout and functional compatibility before substituting with other members of the EQCO series.
