HXR8204-DNT

Overview

The HXR8204-DNT is a four-channel transimpedance limiting amplifier array manufactured by Renesas Electronics. It operates at a maximum data rate of 28 Gbps and is designed for parallel optical links in telecom and datacom applications. The device integrates a transimpedance preamplifier, a limiting post-amplifier, and a versatile CML output stage within a single 3.3V SiGe package.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and CML output stage
• Supports four independent optical input channels
• Designed for high-capacity parallel optical link architectures

Applications

• Telecommunications systems
• Datacom interconnects
• Parallel optical links using PIN detector arrays or discrete detectors

Procurement Notes

Verify the specific suffix DNT against official Renesas documentation to confirm wafer-level packaging requirements and handling procedures. Confirm current production status as legacy ORTA products may have discontinuation notices. Ensure compatibility with existing system power supplies and interface standards before procurement.

Selection Notes

Select this component for designs requiring integrated linear and limiting amplification in a compact form factor. The SiGe technology supports high-speed operation suitable for modern optical networking standards. Evaluate thermal management needs for the integrated amplifier stages and ensure the CML outputs match downstream receiver logic levels.

Part Context

This part belongs to the Optical Receiver Transmitter Array (ORTA) family from IDT, now part of Renesas Electronics. These arrays are specifically engineered to simplify the design of high-speed optical transceivers by combining multiple amplifier stages into a single monolithic solution, reducing board space and component count.
