HXR14400-DNU

Overview

The HXR14400-DNU is a quad-channel linear transimpedance amplifier (TIA) manufactured by Renesas Electronics Corporation. Designed for high-speed optical interconnects, this component supports signaling rates up to 28 Gbaud per channel. It is specifically engineered for use in Ethernet applications and compact form factor modules. The device is supplied as a bare die, intended for direct integration into custom assemblies or optical transceivers.

Feature Summary

• Quad-channel architecture providing four independent linear transimpedance amplifier paths
• Optimized for high-speed data transmission at 28 Gbaud signaling rates
• Designed for integration with clock and data recovery units in optical receivers
• Bare die configuration allows for flexible packaging and module design

Applications

• Ethernet optical transceivers
• High-speed optical interconnect modules
• Data center networking equipment

Procurement Notes

Verify the specific package type and handling requirements for bare die components before procurement. Confirm that the current revision matches system design specifications, as manufacturing changes may occur. Check availability status directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS3 standards if required by your assembly process. Validate pinout and electrical characteristics against the latest official datasheet prior to finalizing orders.

Selection Notes

Select this component when designing quad-channel receiver front-ends for 28 Gbaud Ethernet applications. It is suitable for engineers requiring a linear TIA solution compatible with VCSEL drivers or other optical sources. Consider the bare die format for cost-effective, compact module designs where external packaging is managed by the system integrator. Ensure thermal management strategies account for the die-level implementation.

Part Context

This part belongs to the HXR14400 family of transimpedance amplifiers from Renesas Electronics. It serves as the receiver counterpart to transmitter driver ICs in high-speed optical communication systems. The family is targeted at hyper-scale data centers and high-bandwidth networking infrastructure requiring dense, low-power optical interconnects.

Replacement Considerations

The HXR14400-DNU is listed as obsolete. Verify if the HXR14400-DNT or other updated revisions are available as functional replacements. Consult Renesas for official substitution recommendations to ensure compatibility with existing designs.
