EQCO62R20.3-TRAY

Overview

The EQCO62R20.3 is a 6.25 Gbps asymmetric coax equalizer designed for CoaXPress v1.1 camera standards. It operates on a single 75Ω coax cable, supporting downlink speeds from 1.25 Gbps to 6.25 Gbps and an uplink speed of 21 Mbps. The device features an auto-adaptive equalizer core with variable gain to compensate for cable attenuation. It supports power distribution over the coax up to 900 mA via external inductors. Operating voltage is 1.2V with low power consumption under 70 mW. 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 that automatically detects and adapts to signals with varying 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 support for Power over CoaXPress (PoCXP), allowing power delivery up to 900 mA through the same cable used for data transport.

Applications

• High-definition and high-bandwidth links to cameras
• Machine vision systems for semiconductor chips 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 '.3' against the official Microchip datasheet DS60001302C to confirm package type and material compliance. Ensure the ordering suffix matches the required tape-and-reel or tray configuration if applicable. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when designing CoaXPress v1.1 compliant camera interfaces requiring high-speed data transfer over standard 75Ω coaxial cables. It is suitable for applications needing integrated equalization to extend cable reach without external equalizers. Consider the 1.2V supply requirement and thermal management for the QFN package. Verify compatibility with the paired EQCO62T20 driver for complete link functionality.

Part Context

The EQCO62R20.3 belongs to the EQCO62T/R20 chipset family manufactured by Microchip Technology. This chipset provides a complete solution for bidirectional communication over a single coax cable. The R20 variant specifically functions as the receiver side equalizer, complementing the T20 transmitter driver. It is compatible with legacy and flexible coax types within specified length limits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The EQCO31R20.3 is a lower-speed version with a maximum bit rate of 3.125 Gbps for the high-speed downlink but shares the same uplink speed and interface characteristics.
