EQCO125X40C1TB-I/8EX

Drivers, Receivers, Transceivers Overview

The EQCO125X40C1TB-I/8EX is a CoaXPress 2.0 compliant transceiver manufactured by Microchip Technology, designed for high-speed video transmission applications. It supports data rates up to 12.5 Gbps and operates with a single 1.25 V supply voltage. The device integrates one driver and one receiver within a 16-QFN (4x4 mm) package featuring an exposed pad. It is rated for industrial temperature ranges from -40°C to +85°C and holds AEC-Q100 qualification. This component facilitates full-duplex communication over coaxial cables, supporting both downstream and upstream signal paths simultaneously.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TB' against official Microchip documentation, as standard listings often reference 'I/8EX' or 'I/3DW'. Confirm current production status, as related variants like EQCO125X40C1T-I/8EX are marked obsolete. Ensure compatibility with existing PCB footprints for the 16-QFN package before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when CoaXPress 2.0 compliance and 12.5 Gbps throughput are required. Compare pinout and electrical characteristics with the recommended replacement EQCO125X40C1T-I/3DW if availability is constrained. Verify that the 1.25 V supply requirement aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the EQCO125X40 family of CoaXPress transceivers. It shares core functionality with other variants in the series but differs in packaging and suffix designations. The family is widely used in professional video infrastructure requiring reliable, high-speed serial communication over coaxial media.

Drivers, Receivers, Transceivers Replacement Considerations

Microchip recommends EQCO125X40C1T-I/3DW as a substitute for the EQCO125X40C1T-I/8EX variant. Verify pin-to-pin compatibility and thermal performance differences between the QFN-16 and TRAY packaging options before substitution.
