HXC42400-BFI

Overview

The HXC42400-BFI is a quad-channel Clock and Data Recovery (CDR) and Retimer manufactured by Renesas Electronics. Designed for high-speed data transmission, it supports Ethernet and Fibre Channel applications. The device features four independent channels within a single package. It operates within an industrial temperature range of -40°C to +85°C. The component utilizes a surface-mount mounting type and is housed in an 81-lead FCBGA package with dimensions of 5x5 mm. This integrated circuit serves as a timing support product for signal integrity restoration in high-bandwidth interconnects.

Feature Summary

• Quad-channel architecture providing four independent CDR/Retimer circuits
• Optimized for Ethernet and Fibre Channel main-purpose applications
• Operates reliably across an extended temperature range from -40°C to +85°C
• Packaged in an 81-lead FCBGA (5x5 mm) surface-mount case

Applications

• Ethernet network infrastructure equipment
• Fibre Channel storage area networks
• High-speed serial communication interfaces requiring signal retiming

Procurement Notes

Verify the current lifecycle status before procurement planning, as this specific part number may be subject to discontinuation or limited availability. Confirm that the 81-FCBGA footprint matches the target PCB design constraints. Ensure compatibility with the required operating voltage and temperature specifications for the intended deployment environment. Cross-reference the manufacturer's latest documentation for any end-of-life notifications or recommended alternative components.

Selection Notes

Select this component when a quad-channel solution is required for Ethernet or Fibre Channel signal conditioning. The 81-FCBGA package is suitable for dense board layouts requiring a 5x5 mm footprint. Verify that the system design accommodates the -40°C to +85°C operating range. Consider the pin count and thermal characteristics of the FCBGA package during the initial hardware architecture phase to ensure adequate routing and heat dissipation capabilities.

Part Context

This component belongs to the broader category of Application Specific Clock/Timing products offered by Renesas Electronics. It functions as a timing support device specifically engineered for data recovery and signal reconditioning. Unlike general-purpose clock generators, this IC focuses on restoring signal integrity for high-speed serial links used in networking and storage protocols.

Replacement Considerations

Check the official EOL notification documents for confirmed substitute part numbers. Do not assume functional equivalence with other Renesas CDRs without verifying pinout and electrical parameter alignment.
