HXR6104-DNT

Overview

The HXR6104-DNT is a four-channel transimpedance limiting amplifier array manufactured by Renesas Electronics. Operating at data rates up to 16 Gbps, this SiGe device integrates a transimpedance pre-amplifier, a limiting post-amplifier, and a versatile CML output stage for four optical input channels. Designed for parallel optical links in telecom and datacom applications, it supports QSFP+, 40G Ethernet SR4, and InfiniBand protocols.

Feature Summary

• Integrates transimpedance pre-amplifier, limiting post-amplifier, and CML output stage for four optical channels
• Utilizes silicon-germanium technology for high-performance signal processing
• Designed for compact module assembly with standard silicon technology compatibility

Applications

• QSFP+ modules
• 40G Ethernet SR4 links
• 32G QDR/55G FDR InfiniBand systems

Procurement Notes

Verify the specific suffix DNT against official Renesas documentation to confirm wafer-level packaging and lead-free status. Confirm that the intended application aligns with the specified 0 to 85°C temperature range. Ensure design compatibility with the required 3.3V supply voltage and SiGe process characteristics before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated linear TIA and limiting amplification in a single package. It is suitable for applications needing direct integration with PIN detector arrays or discrete detectors. The CML output stage facilitates easy interfacing with downstream digital logic or serializers in high-speed optical transceiver architectures.
