HXR5004A-DNT-F8

Overview

The HXR5004A-DNT-F8 is a four-channel transimpedance limiting amplifier array from the Optical Receiver Transmitter Array (ORTA) family, designed for parallel optical links. Operating at 10.3 Gbps with a 3.3V SiGe supply, it integrates pre-amplifiers, post-amplifiers, and CML outputs. Key electrical parameters include 20 µApp receiver sensitivity for 10^-12 BER, better than 1.5 mApp overload capability, and 66 mW per channel power consumption in low-power mode. It features adjustable output swing, pre-emphasis, independent RSSI, and QSFP MSA compliance.

Feature Summary

• Integrates transimpedance pre-amplifier, limiting post-amplifier, and versatile CML output stage for four optical channels
• Optimized for isolated and common cathode photo-detector arrays from multiple vendors
• Provides independent Receive Signal Strength Indicator (RSSI) functionality
• Features control lines accessible on both sides of the chip

Applications

• IEEE 802.3ba Ethernet transceivers
• InfiniBand QDR & FDR active cables
• Proprietary multi-channel optical modules

Procurement Notes

Verify component authenticity through authorized Renesas or IDT distributors. Confirm the specific DNT-F8 tape-and-reel packaging variant matches design requirements. Check for End-of-Life status updates as this product line has been discontinued. Ensure compatibility with existing PIN detector arrays before procurement.

Selection Notes

Select this device for high-capacity optical links requiring 10Gb/s data rates. The integrated TIA and limiting amplifier simplify designs compared to discrete solutions. Verify that the 3.3V supply voltage aligns with system power constraints. Consider the bare die package type for custom board integration rather than standard surface-mount packages.

Part Context

This component belongs to the ORTA family targeting parallel optical markets. It complements PIN detector arrays to form complete receiver optical sub-assemblies. The technology utilizes Silicon Germanium processes to achieve high bandwidth and low noise performance suitable for telecom and datacom applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The HXR5004A series is listed as obsolete. Designers should consult official Renesas resources for current alternatives or evaluate legacy inventory availability.
