HXR8201-DNG

Overview

The HXR8201-DNG is a Trans-impedance Limiting Amplifier array designed for single-channel fiber optic links. It operates at 28Gb/s and integrates a transimpedance preamplifier, limiting post-amplifier, and CML output stage. Key electrical parameters include a receiver sensitivity of 60uApp for 10^-12 BER at 28Gbps and an overload capability greater than 2.4mApp. Power consumption is 141mW per channel with low power settings. The device supports automatic gain and threshold controls, adjustable output swing, and programmable thresholds with SQUELCH functionality.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and versatile CML output stage in a single 3.3V SiGe device.
• Features automatic gain and threshold controls alongside adjustable output swing size and pre-emphasis mode.
• Includes Signal Detect and independent RSSI capabilities optimized for isolated and common cathode photo-detector arrays.
• Complies with QSFP MSA standards and offers control lines accessible on both sides of the chip.

Applications

• Single channel fiber optic links
• Datacom applications
• 100G to 25G fan-out applications

Procurement Notes

Verify current availability status as the HXR8201 series has been marked as obsolete or discontinued by Renesas Electronics. Confirm if the specific DNG package variant is still supported or if alternative end-of-life management procedures apply. Ensure compatibility with existing system designs before procurement attempts due to potential supply chain constraints.

Selection Notes

Select this component for high-capacity optical links requiring integrated TIA and PA functions. It is suitable for designs needing 28Gb/s performance with low power consumption. Consider its compliance with QSFP MSA and support for various photo-detector arrays when evaluating system integration requirements.
