HXR14100-DNU

Overview

The HXR14100-DNU is a single-channel linear Trans-Impedance Amplifier (TIA) from Renesas' Optical Receiver Transmitter Array (ORTA) family. It supports 56Gbps PAM4 Ethernet applications with low power consumption as low as 140mW/ch. The device features up to 5kΩ typical differential gain, wide adjustable output voltage swing, and linear operation up to 3mAppSE overload with internal AGC. It offers up to 30GHz typical bandwidth and 9pA/√Hz input-referred current noise density. Operating temperature range is -5°C to 95°C.

Feature Summary

• High receiver sensitivity for 56Gbps PAM4 Ethernet applications
• Low power mode in 28Gbaud applications
• Linear operation up to 3mAppSE overload with internal AGC
• RSSI, LOS, and Rx disable functions

Applications

• Next-generation 200G optical transceivers
• Compact linear Receiver Optical Sub-Assembly (ROSA) design
• 28GBaud PAM4 data rate systems

Procurement Notes

Verify the specific suffix DNU against official Renesas documentation to confirm the operating temperature range of -5°C to 95°C. Confirm package type is WFP and lead count is 0. Check current status as Obsolete and availability through authorized channels. Ensure compliance with Pb Free and RoHS requirements specified for this variant.

Selection Notes

Select this component for designs requiring a single-channel linear TIA with high bandwidth and low noise. Consider the -5°C to 95°C industrial temperature range suitability. Evaluate power consumption needs against the 140mW/ch specification. Verify compatibility with PIN detectors for ROSA integration. Assess interface requirements for RSSI, LOS, and Rx disable functions.

Part Context

The HXR14100 belongs to Renesas' ORTA product family, designed for high-speed optical interconnects. It complements other components like the HXT14450 retimer for complete transceiver solutions. This TIA enables compact module designs for data center applications using advanced modulation schemes.

Replacement Considerations

The part status is listed as Obsolete. Consult official Renesas documentation for recommended migration paths or alternative components within the ORTA family that support similar specifications and form factors.
