HXR6104R-DNT

Overview

The HXR6104R-DNT is a four-channel linear transimpedance amplifier (TIA) array manufactured by Renesas Electronics. Designed for high-speed optical receiver applications, this component supports data rates up to 16 Gbps per channel. It integrates the TIA pre-amplifier and limiting post-amplifier with a versatile CML output stage. The device operates on a single 3.3V supply using SiGe technology and is supplied as a bare die in wafer form.

Feature Summary

• Integrates four independent optical input channels with linear TIA and limiting post-amplifier stages
• Features versatile CML output stage for high-speed signal transmission
• Utilizes silicon-germanium (SiGe) technology for optimized performance
• Designed for parallel optical links in telecom and datacom environments

Applications

• QSFP+ optical modules
• 40G Ethernet SR4 systems
• 32G QDR InfiniBand networks
• 55G FDR InfiniBand networks

Procurement Notes

Verify the specific suffix 'R' against official Renesas documentation to confirm any functional differences from the standard HXR6104 variant. Ensure compatibility with wire bonding processes, as this is a bare die component requiring specific PCB substrate integration and decoupling capacitor placement for optimal ESD protection and signal integrity.

Selection Notes

Select this component for designs requiring integrated four-channel reception at 16 Gbps speeds. It is suitable for replacing discrete amplifier solutions to reduce board space. Consider the need for external PIN detector arrays or discrete detectors to complete the optical link design. Verify thermal management requirements within the 0 to 85°C operating range.

Part Context

This part belongs to Renesas' Optical Receiver Transmitter Array (ORTA) product family. These devices are engineered specifically for the parallel optical links market, targeting high-capacity and high-availability optical interconnects. The series includes complementary driver components like the HXT6104 for complete transmitter-receiver system solutions.
