HXR6101-DNT

Overview

The HXR6101-DNT is a single-channel laser driver and transimpedance amplifier (TIA) receiver manufactured by Renesas Electronics. Designed for optical interconnects, it supports data rates up to 16 Gb/s. The device integrates a TIA pre-amplifier, a limiting post-amplifier, and a CML output stage within a 3.3V SiGe process. It is intended for use with PIN detectors in high-capacity, high-availability optical links for datacom applications.

Feature Summary

• Integrates transimpedance pre-amplifier, limiting post-amplifier, and CML output stage
• Supports 16 Gb/s data rate operation
• Operates on a 3.3V supply using SiGe technology
• Designed for single-channel optical link applications

Applications

• Datacom optical links
• High-capacity optical interconnects
• Modules utilizing PIN detector arrays or discrete detectors

Procurement Notes

This component is officially designated as End-of-Life (EOL). A Product Discontinuance Notification has been issued, indicating that the manufacturer will cease production. Availability is restricted, and sourcing new units may be difficult. Engineers should verify current stock status with authorized distributors and prepare for design migration to alternative components immediately.

Selection Notes

Select this part only if legacy compatibility is required and EOL constraints are acceptable. Verify that the single-channel architecture meets system requirements. Ensure the 3.3V SiGe process aligns with existing thermal and power budgets. Confirm that the CML output interface matches downstream logic levels. Evaluate replacement options early due to discontinuation status.

Part Context

The HXR6101 belongs to the IDT family of Optical Receiver Transmitter Array (ORTA) products, now under Renesas Electronics. It targets the parallel optical links market, offering a compact solution for converting optical signals to electrical CML outputs. It complements other ORTA devices like the multi-channel HXR6112.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, consult Renesas sales representatives for recommended alternatives or updated product briefs.
