EQCO125X40C1-I/3DW

Overview

The EQCO125X40C1-I/3DW is a CoaXPress 2.0 compliant transceiver manufactured by Microchip Technology, designed for high-speed serial communication in machine vision systems. It supports data rates up to 12.5Gbps and operates with a single 1.25V supply voltage. The device integrates one driver and one receiver within a 16-VQFN package measuring 4x4 mm. It features an integrated Clock Data Recovery (CDR) circuit and supports full-duplex communication over a single coaxial cable. The component is qualified under AEC-Q100 standards and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates CoaXPress 2.0 standard compliance with backward compatibility for lower speed levels.
• Includes built-in Clock Data Recovery (CDR) to enhance signal integrity and jitter performance.
• Supports simultaneous power delivery and bidirectional data transmission over a single cable.
• Features integrated link signal integrity testing for real-time cable health monitoring.

Applications

• Industrial inspection and automated quality control systems
• Traffic monitoring and surveillance infrastructure
• Medical imaging and diagnostic equipment

Procurement Notes

Verify the specific suffix 'I/3DW' against current manufacturer documentation to confirm package type and commercial grade status. Check for Product Change Notices regarding packaging or pinout modifications. Confirm availability status as distribution channels may list obsolete variants alongside active ones. Ensure the source document explicitly identifies this part number as the primary reference for technical specifications.

Selection Notes

Select this component when designing systems requiring CoaXPress 2.0 compliance with integrated CDR capabilities. It is suitable for applications needing extended cable lengths and reduced latency compared to previous generations. Consider the 16-VQFN footprint for space-constrained PCB layouts. Verify that the system architecture can support the 1.25V supply requirement and utilizes the single-cable power and data transmission feature.

Part Context

This device belongs to the EQCO125X40 family, which represents Microchip's first generation of CoaXPress 2.0 devices. The family enables significant throughput improvements over legacy solutions by supporting higher bandwidth on a single channel. It addresses the need for simplified cabling and reduced complexity in high-performance machine vision setups.

Replacement Considerations

The EQCO125X40C1T-I/8EX is listed as a discontinued alternative. Designers should evaluate the EQCO125X40C1T-I/3DW as a recommended manufacturer substitute if sourcing from distributors listing obsolete inventory. Verify pin-to-pin compatibility and electrical parameter alignment before implementation.
