HXR42100-DNT

Overview

The HXR42100-DNT is a transimpedance limiting amplifier array from the Optical Receiver Transmitter Array (ORTA) family, manufactured by Renesas Electronics. It is designed for single-channel fiber optic links and integrates a transimpedance preamplifier, a limiting post-amplifier, and a versatile CML output stage to support a single differential electrical channel. The device operates on a 3.3V supply using SiGe technology. It is intended for use with discrete PIN detector arrays to create high-capacity optical links.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and CML output stage in a single device
• Supports single differential electrical channel output
• Designed for integration with discrete PIN detector arrays
• Utilizes Silicon Germanide (SiGe) technology

Applications

• Single channel fiber optic links
• Datacom applications
• 100G to 25G fan-out applications

Procurement Notes

Verify the specific suffix -DNT against official Renesas documentation to confirm package type and lead-free status. Ensure compatibility with discrete PIN detector arrays for your target optical link design. Confirm that the application environment falls within the specified operating temperature range of 0 to 70°C. Check for any specific handling requirements associated with the wafer or dice packaging format.

Selection Notes

Select this component when designing high-availability optical links requiring integrated amplification for single-channel fiber optic systems. It is suitable for datacom environments where a combined TIA and limiting amplifier reduces component count. Consider the 3.3V power requirement and SiGe process characteristics. Evaluate the need for CML outputs and differential signaling capabilities for your interface requirements.

Part Context

The HXR42100-DNT belongs to the ORTA product family, which targets the single-channel fiber optic links market. This series enables the design of high-capacity optical links when paired with discrete PIN detectors. The device represents a specialized solution for optical receiver front-ends in data communication infrastructure.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers within the ORTA family or equivalent transimpedance amplifier arrays. Verify pinout and functional compatibility before considering alternatives.
