EQCO125X40C1T-I/3DW

Overview

The EQCO125X40C1T-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 12.5 Gbps and operates within a supply voltage range of 1.25V. The device integrates one driver and one receiver in a full-duplex configuration, housed in a 16-QFN (4x4 mm) package with exposed pad. It functions as an equalizer, repeater, or transmitter/receiver, supporting synchronous complementary upstream links at 20.833 Mbps or 41.66 Mbps using 8b/10b encoding. The component is rated for industrial temperatures from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Integrates clock data recovery (CDR) functionality across all speed levels from CXP-1 to CXP-12, ensuring seamless frequency locking and improved signal jitter performance.
• Supports bidirectional communication over a single coaxial cable, enabling simultaneous power delivery and data transmission between camera devices and host acquisition cards.
• Includes integrated link signal integrity testing capabilities, allowing real-time verification of cable and link health before and during system operation.

Applications

• High-throughput industrial machine vision inspection systems
• Traffic monitoring and surveillance infrastructure
• Medical imaging and diagnostic equipment requiring low latency

Procurement Notes

Verify the specific suffix 'C1T' against the manufacturer's latest datasheet to confirm tape-and-reel packaging status, as standard variants may differ. Ensure compatibility with existing PCB footprints for the 16-QFN package. Confirm that the selected distributor provides genuine Microchip Technology components to avoid counterfeit risks associated with high-speed interface ICs.

Selection Notes

Select this component when designing CoaXPress 2.0 compliant systems requiring up to 12.5 Gbps throughput on a single channel. It is suitable for replacing legacy solutions where distance limitations or multi-cable complexity are constraints. Consider the integrated CDR and link testing features if system reliability and simplified FPGA clock programming are priorities.

Part Context

This part belongs to the EQCO125X40 family, which represents Microchip's first generation of CoaXPress 2.0 devices. The family is designed to offer backward compatibility while providing significantly higher bandwidth and lower power consumption compared to previous generations. It serves as a key enabler for next-generation machine vision applications demanding higher frame rates and longer cable runs.

Replacement Considerations

The EQCO125X40C1T-I/8EX is listed as a discontinued alternative by the manufacturer, with the EQCO125X40C1T-I/3DW recommended as the replacement. Verify pinout and thermal characteristics when transitioning between different package options within the same functional family.
