HXR8204-DNG

Overview

The HXR8204-DNG is a four-channel Transimpedance Limiting Amplifier (TIA) array designed for high-speed optical receiver applications. Operating at data rates up to 28 Gbps, this SiGe device integrates the transimpedance preamplifier, limiting post-amplifier, and CML output stage on a single chip. It delivers a receiver sensitivity of 60 mApp for a bit error rate of 10^-12 and maintains an overload threshold better than 2.4 mApp. Power consumption is specified at 141 mW per channel. The component supports adjustable output swing, pre-emphasis, and signal detect thresholds, ensuring compatibility with various photo-detector arrays.

Feature Summary

• Integrates transimpedance preamplifier, limiting post-amplifier, and versatile CML output stage for four optical channels
• Provides adjustable output swing size and pre-emphasis in limiting mode along with signal detect threshold control
• Features independent RSSI and control lines accessible on both sides of the chip for design flexibility
• Optimized for use with isolated and common cathode photo-detector arrays from multiple vendors

Applications

• Parallel optical links for telecom and datacom applications
• QSFP MSA compliant modules
• High-capacity optical links using PIN detector arrays or discrete detectors

Procurement Notes

Verify the specific suffix DNG against official Renesas documentation to confirm package type and temperature range specifications. Ensure the procurement source provides valid traceability for wafer-level components. Confirm that the active status aligns with current production announcements. Request the latest preliminary datasheet to validate any recent parameter updates or design changes before finalizing integration plans.

Selection Notes
