EQCO125T40C1T-I/8EX

Overview

The EQCO125T40C1T-I/8EX is a single-chip asymmetric equalizer, driver, and repeater designed for high-speed signaling applications. It supports downstream bit-rates from 1.25 Gbps to 12.5 Gbps and simultaneous uplink rates of 20.833 Mbps or 41.666 Mbps. The device operates on a single 1.25 V supply and features an integrated auto-adaptive equalizer and reference-less Clock-Data Recovery (CDR) to restore signal integrity. It is housed in a 16-pin QFN package with a 0.65 mm pitch and is rated for industrial temperature ranges.

Feature Summary

• Supports CoaXPress standards including CXP-1 through CXP-12 speeds
• Enables simultaneous power transmission over coax alongside data signals
• Includes integrated termination resistors for differential signaling
• Operates without external reference clocks or crystals

Applications

• CoaXPress compliant camera links
• High-definition camera connections
• Links between FPGAs
• Machine vision systems
• Broadcast and surveillance cameras

Procurement Notes

Verify the specific ordering suffix against current Microchip documentation to confirm package type and tape-and-reel configuration. Confirm that the component meets the required environmental specifications for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this model when a lower-cost transmitter-only solution is required for the device side of a link. Ensure the application utilizes 8b/10b coding and requires support for up to 12.5 Gbps downlink speeds. Verify compatibility with the target cable types such as 75 ohm coaxial or shielded twisted pair.

Part Context

This component belongs to the EQCO125X40 family of asymmetric equalizers and drivers. It shares core functionality with the EQCO125X40 but is optimized for cost-effective implementation on the device side of communication links. The family supports various CoaXPress speeds and generic high-speed serial transport applications.

Replacement Considerations

Microchip recommends the EQCO125X40C1T-I/3DW as a replacement part number.
