EQCO31R20.3

Overview

The EQCO31R20.3 is a CoaXPress receiver component designed for bidirectional communication over a single 75Ω coaxial cable. It supports downlink data rates up to 3.125 Gbps and an uplink speed of 21 Mbps. The device operates on a 1.2V supply with low power consumption below 70 mW. It features an adaptive equalizer, integrated termination resistors, and clock-data recovery capabilities. The chip is housed in a 16-pin QFN package and complies with the CoaXPress v1.1 standard.

Feature Summary

• Supports full-duplex bidirectional data transmission over a single coaxial cable
• Includes an auto-adaptive equalizer core for signal restoration
• Enables simultaneous power distribution over the coax cable
• Operates without external reference clocks

Applications

• High-definition camera links
• Machine vision inspection systems
• Military and aerospace applications
• Broadcast and surveillance camera systems
• Traffic monitoring systems

Procurement Notes

Verify that the specific part number matches the required datasheet revision. Confirm the operating temperature range requirements align with the industrial specification. Ensure the design accommodates the necessary external passive components for RF performance. Check for any specific ordering suffixes that may affect packaging or compliance status.

Selection Notes

Select this component for the host side of a CoaXPress link where high-speed reception is required. It pairs with the EQCO31T20 transmitter for symmetric speeds up to 3.125 Gbps. Consider the PCB layout constraints for optimal RF performance. Evaluate the need for Power over CoaXPress support if powering remote devices.

Part Context

This device belongs to the EQCO62T/R20 chipset family from Microchip Technology. It serves as the receiver counterpart to the EQCO31T20 driver. The chipset facilitates long-distance video transmission using standard coaxial cables. It is specifically engineered for machine vision and industrial imaging applications requiring high bandwidth.

Replacement Considerations

The EQCO62R20.3 is a higher-speed variant within the same family. Verify compatibility if substituting between the 3.125 Gbps and 6.25 Gbps versions. Both share similar pinouts and operational principles.
