EQCO62X20C1T-I/8EX

Overview

The EQCO62X20C1T-I/8EX is a CoaXPress equalizer designed for bidirectional communication over a single 75Ω coax cable. It supports downlink speeds from 1.25 Gbps to 6.25 Gbps and an uplink speed of 21 Mbps. The device operates on a 1.2V supply with low power consumption under 70 mW. It features an auto-adaptive equalizer core, variable gain, and multi-speed capabilities. The component is housed in a 16-pin QFN package (4x4 mm) and supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Auto-adaptive equalizer core compensates for cable attenuation using a time-continuous feedback loop
• Supports full-duplex bidirectional data channels over a single coaxial cable
• Compatible with Power over CoaXPress (PoCXP) standards for simultaneous power delivery
• Integrated active signal splitter/combiner with internal termination resistors

Applications

• High-definition camera links in machine vision systems
• Semiconductor chip and display panel inspection equipment
• Military, aerospace, and medical imaging applications
• Broadcast and surveillance camera networks
• Traffic monitoring and license plate recognition systems

Procurement Notes

Verify the specific suffix 'I/8EX' against official Microchip documentation to confirm temperature range and packaging details. Ensure compatibility with the host frame grabber's CoaXPress implementation. Confirm that the required external components, such as ferrite beads and inductors, meet the RF performance specifications outlined in the datasheet.

Selection Notes

Select this component when designing high-bandwidth camera interfaces requiring long-distance transmission over standard coaxial cables. It serves as the receiver-side counterpart to the EQCO62T20 driver. Consider the 16-pin QFN footprint constraints during PCB layout planning. Verify that the system design accommodates the necessary external passive components for optimal signal integrity.

Part Context

This part belongs to the EQCO62T/R20 chipset family developed by Microchip Technology. It is specifically engineered to comply with the CoaXPress v1.1 camera standard. The chipset enables asymmetric data transfer, handling high-speed downlinks and lower-speed uplinks simultaneously. It represents a solution for integrating cameras into complex industrial and scientific imaging architectures.
