EQCO125T40C1T-I/3DW

Overview

The EQCO125T40C1T-I/3DW is a CoaXPress 2.0 transmitter integrated circuit manufactured by Microchip Technology, designed for high-speed video transmission applications. It supports data rates up to 12.5 Gbps and operates within an industrial temperature range of -40°C to +85°C. The device utilizes a 16-VQFN package with dimensions of 4x4 mm and requires a 1.25V supply voltage. It features full-duplex communication capabilities, integrating one driver and one receiver on a single chip to facilitate efficient signal transmission in camera-to-host architectures.

Feature Summary

• Supports CoaXPress 2.0 standard for high-bandwidth video transmission
• Integrates transmitter and receiver functions on a single chip
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial machine vision systems requiring high-speed data links
• Camera interfaces for image acquisition cards
• Medical imaging equipment demanding reliable video transmission

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'I' designation aligns with required industrial temperature specifications. Ensure compatibility with existing PCB footprints for the 16-QFN package. Check for RoHS compliance status relevant to your manufacturing region. Validate that the 1.25V power supply requirements match your system design.

Selection Notes

Select this component when CoaXPress 2.0 compliance is mandatory for the application. Choose this part over receivers if the design requires active signal driving capabilities. Consider the 12.5 Gbps limit when evaluating bandwidth needs against longer cable runs. Verify that the single-channel architecture meets the system's channel count requirements without needing additional multiplexing.

Part Context

This component belongs to the EQCO125x40 family of equalizers and drivers from Microchip Technology. The family includes variants such as the EQCO125X40C1-I/3DW, which serves similar functions but may differ in packaging or revision details. These devices are engineered specifically for the CoaXPress ecosystem, providing standardized solutions for high-speed serial communication in professional imaging environments.

Replacement Considerations

The EQCO125X40C1T-I/3DW is listed as a manufacturer-recommended alternative. Verify pinout compatibility before substitution. Ensure the replacement part maintains the same thermal and electrical characteristics for the target application.
