EQCO31R20.3-TRAY

Overview

The EQCO31R20.3 is a CoaXPress v1.1 compliant receiver equalizer 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 under 70 mW. It features an auto-adaptive equalizer core, variable gain, and multi-speed capabilities. The component is housed in a 16-pin, 4x4 mm QFN package with a 0.65 mm pin pitch.

Feature Summary

• Auto-adaptive equalizer core compensates for cable attenuation using a time-continuous feedback loop
• Supports full-duplex bidirectional data transmission over a single 75Ω coax cable
• Integrated low-speed transmitter for precise triggering events via the uplink channel
• Compatible with Power over CoaXPress (PoCXP) for simultaneous power distribution

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 license plate recognition and monitoring systems

Procurement Notes

Verify the specific suffix '.3' indicates the correct package variant and revision level required for your design. Confirm that the 'TRAY' designation aligns with your manufacturing handling requirements. Ensure compatibility with the 1.2V supply voltage and check for any silicon errata sheets relevant to this specific part number before finalizing procurement.

Selection Notes

Select the EQCO31R20.3 when a maximum downlink rate of 3.125 Gbps meets system bandwidth needs. This model serves as the receiver counterpart to the EQCO31T20 driver. Consider the lower-speed uplink capability for control signals. Evaluate PCB layout constraints due to the small QFN footprint and critical RF performance requirements.

Part Context

This component belongs to the EQCO62T/R20 chipset family developed by Microchip Technology. While the EQCO62R20 supports higher speeds up to 6.25 Gbps, the EQCO31R20.3 is optimized for 3.125 Gbps applications. Both share identical packaging and interface characteristics, allowing for flexible system scaling based on bandwidth requirements.

Replacement Considerations

The EQCO62R20.3 is a higher-speed alternative within the same family. Verify if the increased 6.25 Gbps capability is necessary or if it introduces unnecessary complexity. No other direct substitutes are documented in the official datasheet.
