HXR8212-DNT

Overview

The HXR8212-DNT is a Trans-impedance Limiting Amplifier array belonging to the Optical Receiver Transmitter Array (ORTA) product family. Manufactured by Renesas Electronics, this component integrates a transimpedance preamplifier, a limiting post-amplifier, and a versatile CML output stage for four optical channels. Designed as a 3.3V SiGe device, it targets high-capacity, high-availability optical links for telecom and datacom applications when used with PIN detector arrays or discrete detectors.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and CML output stage
• Supports four optical channels in a single device
• Compatible with PIN detector arrays or discrete detectors

Applications

• Telecom optical links
• Datacom optical links
• Parallel optical links

Procurement Notes

Verify current availability status as the part may be subject to discontinuation notices. Confirm package type and temperature range specifications against official datasheets before integration. Ensure compatibility with existing PIN detector arrays or discrete detectors for proper system function.

Selection Notes

Select this component for designs requiring integrated TIA and limiting amplifier functions for four-channel optical receivers. The SiGe technology supports 3.3V operation suitable for standard telecom and datacom voltage rails. Evaluate interface requirements for the CML output stage to ensure compatibility with downstream logic.

Part Context

This part is part of the ORTA family targeted at parallel optical links. It serves as an optical receiver solution complementing transmitter components like the HXT series. The device simplifies design by combining multiple amplifier stages into one SiGe chip.

Replacement Considerations

Check for official End-of-Life (EOL) notifications from Renesas. Verify if newer ORTA family members offer equivalent channel counts and performance metrics.
