HXC42200-BFI

Overview

The HXC42200-BFI is a dual-channel CDR/Retimer manufactured by Renesas Electronics, designed for high-speed serial data applications. It supports bi-directional operation with data rates ranging from 51 Gbps to 56 Gbps using PAM-4 signaling. The device is optimized for 50Gbps Ethernet and OIF CEI-56G-VSR standards, featuring low power consumption of less than 250mW per channel at 56Gbps. It integrates programmable adaptive equalization in the receiver and de-emphasis in the transmitter to compensate for channel insertion loss and inter-symbol interference. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 49-ball FCBGA package.

Feature Summary

• Dual-channel PAM-4 CDR/Retimer supporting 51–56 Gbps data rates
• Integrated 14GHz master VCO enabling reference-less or master-channel-less operation
• Adaptive CTLE (up to 7 dB) and 1-tap DFE for receive equalization
• Programmable 3-tap FIR de-emphasis with 9 dB control range for transmit

Applications

• 50Gbps Ethernet links
• OIF CEI-56G-VSR compliant modules
• High-speed optical transceivers requiring retiming

Procurement Notes

The HXC42200-BFI is listed as an End-of-Life (EOL) product by Renesas Electronics. Availability is restricted, and Mouser indicates limited supply status. Designers should verify current stock levels and lead times directly with authorized distributors. Due to its discontinued status, long-term procurement planning requires caution, and alternative solutions may need to be evaluated for new designs.

Selection Notes

This component is suitable for systems requiring dual-channel retiming at 56Gbps PAM-4 speeds. It offers independent RX/TX CDR loop bandwidth optimization for improved jitter tolerance. The built-in BIST functions, including PRBS generator/checker and Eye Open Monitor, facilitate module-level testing. Selection should consider the 49-FCBGA footprint and the requirement for I2C configuration via the internal state machine.

Part Context

The HXC42200 belongs to the HXC44200 series family. While datasheets often describe the HXC44200 variant, the HXC42200-BFI shares the same core architecture for dual-channel PAM-4 retiming. Both variants target similar high-speed Ethernet and optical networking applications, providing comparable equalization capabilities and low-power performance characteristics within the same package form factor.

Replacement Considerations

As the HXC42200-BFI is discontinued, engineers must evaluate compatible alternatives from Renesas or other vendors that support 56Gbps PAM-4 dual-channel retiming. Verify pin compatibility, electrical specifications, and software configurability when migrating to successor devices or cross-vendor solutions.
