EQCO125T40C1TB-I/8EX

Overview

The EQCO125T40C1TB-I/8EX is a CoaXPress 2.0 compliant transmitter component manufactured by Microchip Technology, designed for high-speed asymmetric full-duplex communication in machine vision systems. It supports data rates up to 12.5 Gbps over a single coaxial cable, eliminating the need for multiple channels. The device integrates clock-data recovery (CDR) and operates on a single 1.25V supply. Packaged in a 16-pin QFN with a 0.65mm pin pitch, it functions within an industrial temperature range of -40°C to +85°C and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Supports CoaXPress 2.0 standard with integrated CDR for signal integrity restoration
• Enables asymmetric full-duplex communication using a single cable link
• Operates without external reference clocks or crystals
• Provides low power consumption via single 1.25V supply

Applications

• High-definition camera links in industrial inspection systems
• Connections between FPGAs requiring high bandwidth
• Traffic monitoring and security surveillance networks
• Medical imaging and embedded vision solutions

Procurement Notes

Verify the specific suffix 'TB' against official Microchip documentation to confirm tape-and-reel packaging configuration. Confirm that the 'I/8EX' designation aligns with the intended industrial temperature grade and RoHS compliance status. Cross-reference the part number with current manufacturer lifecycle notices to ensure availability and check for any recommended replacements due to obsolescence.

Selection Notes

Select this component when designing CoaXPress 2.0 compliant links requiring transmitter-only functionality on the device side. Ensure the system design accommodates the 16-QFN package footprint and thermal requirements. Verify compatibility with the host receiver unit, such as the EQCO125X40 series, to maintain symmetric protocol support and optimal signal performance across the selected cable type.

Part Context

This part belongs to the EQCO125X40 family, which represents Microchip's first CoaXPress 2.0 devices. The family enables four to eight times faster transmission speeds compared to previous solutions while reducing power consumption. These components are engineered to extend cable distances significantly and improve jitter performance through integrated clock recovery mechanisms suitable for demanding industrial environments.

Replacement Considerations

Microchip recommends the EQCO125X40C1T-I/3DW as a replacement for similar family members. Verify functional equivalence and pinout compatibility before substitution. Check for updated manufacturing dates and packaging variations.
