HXR5104A-DNT-F8

Overview

The HXR5104A-DNT-F8 is a four-channel transimpedance limiting amplifier array from Renesas Electronics Corporation, designed for high-speed optical receiver applications. Operating at data rates up to 12.5 Gbps per channel, this SiGe device integrates the transimpedance preamplifier, limiting post-amplifier, and CML output stage on a single die. It is optimized for use with PIN detector arrays or discrete detectors in parallel optical links. The component supports 3.3V operation and features adjustable output swing and signal detect thresholds. It complies with QSFP MSA standards, making it suitable for telecom and datacom infrastructure requiring high capacity and availability.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and versatile CML output stage for four optical channels
• Optimized for isolated and common cathode photo-detector arrays from multiple vendors
• Features adjustable output swing size, pre-emphasis mode, and independent RSSI
• Complies with QSFP MSA standards for module design flexibility

Applications

• Telecommunications optical links
• Datacom parallel optical links
• QSFP compliant modules
• High-capacity optical interconnects

Procurement Notes

Verify the specific suffix -F8 against official Renesas documentation to confirm package configuration and handling requirements. Confirm current lifecycle status as older ORTA family members may be subject to end-of-life processes. Ensure compatibility with intended photodetector arrays before procurement. Check for any recent product change notices affecting electrical characteristics or pin assignments.

Selection Notes

Select the HXR5104A-DNT-F8 when designing 10G to 12.5G per channel optical receivers requiring integrated limiting amplification. Consider this part for applications needing independent RSSI monitoring and adjustable signal parameters. Evaluate power consumption constraints, as the device offers low-power settings. Ensure the system architecture supports the required 3.3V supply and CML interface standards.

Part Context

The HXR5104A belongs to the Optical Receiver Transmitter Array (ORTA) family from Renesas, targeting the parallel optical links market. This family includes various TIA and driver solutions for different data rates and form factors. The HXR series specifically focuses on receiver-side amplification, complementing transmitter drivers like the HXT series to complete optical link designs.

Replacement Considerations

Check for newer ORTA family members with higher data rate support if future-proofing is required. Verify if the HXR6104 series serves as a direct functional replacement for 16Gbps applications. Consult Renesas for obsolete part substitution programs if the HXR5104A is discontinued.
