EQCO125X40C1TB-I/3DW

Overview

The EQCO125X40C1TB-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 from 1.25 Gbps to 12.5 Gbps using 8b/10b encoding. The device integrates a single driver and receiver in a full-duplex configuration within a 16-QFN package. It operates on a 1.25 V supply voltage and functions reliably across an industrial temperature range of -40°C to +85°C. Key technical features include integrated Clock Data Recovery (CDR) and support for asymmetric bidirectional communication over a single coaxial cable.

Feature Summary

• Integrates CoaXPress 2.0 standard compliance with backward compatibility for lower speed variants.
• Features built-in Clock Data Recovery (CDR) and camera-side clock recovery capabilities.
• Supports link signal integrity testing for real-time cable quality verification.

Applications

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

Procurement Notes

Verify the specific suffix 'TB' against official Microchip documentation, as standard listings typically utilize 'T' or no trailing letter for tape-and-reel packaging. Confirm current production status, as related family members have faced obsolescence notices. Ensure the selected variant matches the required package type and thermal specifications for the target application environment.

Selection Notes

Select this component when designing CoaXPress 2.0 compliant vision systems requiring up to 12.5 Gbps throughput. It is suitable for replacing legacy CXP-1 through CXP-12 solutions due to its seamless locking capability across frequencies. Consider the integrated CDR and low latency benefits for applications demanding precise signal timing without external FPGA clock programming.

Part Context

This part belongs to the EQCO125X40 family, which represents Microchip's first CoaXPress 2.0 devices. The series enables four to eight times faster transmission speeds compared to previous generations while reducing power consumption. These components are engineered to extend cable link distances significantly, supporting system scalability in high-performance visual processing environments.

Replacement Considerations

Microchip recommends the EQCO125X40C1T-I/3DW as a manufacturer-approved alternative for discontinued variants like the EQCO125X40C1T-I/8EX. Verify pinout and electrical compatibility before substitution, as package changes may impact PCB layout requirements.
