EQCO62X20C1-I/8EX

Overview

The EQCO62X20C1-I/8EX is a CoaXPress receiver component designed for bidirectional communication over a single 75Ω coaxial cable. It supports downlink data rates from 1.25 Gbps to 6.25 Gbps and an uplink rate of 21 Mbps. The device features an auto-adaptive equalizer core that compensates for cable attenuation and frequency response variations. It operates on a 1.2V supply with low power consumption below 70 mW. The component is housed in a 16-pin, 4x4 mm QFN package with a 0.65 mm pin pitch and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Auto-adaptive equalizer core that automatically detects and adjusts to varying signal edge rates, attenuation levels, and cable characteristics using a time-continuous feedback loop.
• Full-duplex bidirectional data channel enabling simultaneous high-speed downlink transmission and lower-speed uplink signaling over a single coaxial cable.
• Integrated active signal splitter/combiner that subtracts the transmit output from the received signal to isolate the far-end transmit signal.
• Compatibility with Power over CoaXPress (PoCXP) standards, allowing power distribution over the same cable used for data transport.

Applications

• High-definition and high-bandwidth camera links
• Machine vision systems for semiconductor chip and display panel inspection
• Military, aerospace, and medical imaging applications
• Broadcast and surveillance camera systems
• Traffic license plate recognition and monitoring systems

Procurement Notes

Verify the specific suffix 'I/8EX' against official Microchip documentation to confirm industrial temperature rating and tape-and-reel packaging configuration. Ensure compatibility with the required 1.2V supply voltage and check for any specific ordering restrictions or lead times associated with this variant. Confirm RoHS compliance status as stated in the datasheet.

Selection Notes

Select this component for applications requiring a CoaXPress v1.1 compliant receiver side of the link. It is suitable for frame grabber designs needing to receive high-speed video data while transmitting control signals. Consider the PCB layout requirements for RF performance and the need for external inductors and ferrite beads if implementing Power over CoaXPress functionality.

Part Context

This device belongs to the EQCO62T/R20 chipset family, which provides single-chip solutions for both camera and frame grabber sides of a CoaXPress connection. The R20 variant specifically serves as the receiver/equalizer, complementing the T20 driver/transmitter. It enables long-distance connections over standard 75Ω coaxial cables, supporting various cable types including thin, flexible lightweight options.

Replacement Considerations

The EQCO31R20.3 is a lower-speed version of the EQCO62R20.3, supporting a maximum downlink bit rate of 3.125 Gbps while maintaining the same uplink speed. Verify if the reduced bandwidth meets system requirements before substitution.
