HXR8204-QUAL

Overview

The HXR8204-QUAL is a qualified variant of the HXR8204 Transimpedance Limiting Amplifier array, designed for parallel optical links. It operates at data rates up to 28 Gbps with four channels. The device integrates a transimpedance preamplifier, limiting post-amplifier, and CML output stage in a 3.3V SiGe process. Key electrical specifications include a receiver sensitivity of 60 mApp for a 10^-12 BER and an overload capability better than 2.4 mApp. Power consumption is limited to 141 mW per channel. The component supports adjustable output swing, pre-emphasis, and independent RSSI.

Feature Summary

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

Applications

• QSFP MSA compliant modules
• Telecom parallel optical links
• Datacom high-capacity optical interconnects

Procurement Notes

Verify that the specific suffix '-QUAL' denotes qualification status rather than a functional change, as datasheets typically list 'HXR8204-DNG'. Confirm package type is WAFER and lead count is zero. Ensure temperature range matches -40 to 105°C. Check for RoHS compliance (e3 Sn). Validate active status and availability through official Renesas channels.

Selection Notes

Select this component for applications requiring low power consumption and high sensitivity in 28Gbps optical receivers. It is suitable for designs using PIN detector arrays or discrete detectors. Consider the 3.3V SiGe technology and QSFP MSA compliance when designing for telecom and datacom markets. Verify compatibility with specific vendor photo-detector arrays.

Part Context

The HXR8204 belongs to IDT’s Optical Receiver Transmitter Array (ORTA) product family, now part of Renesas Electronics. It is targeted at the parallel optical links market. The standard version is designated HXR8204-DNG. The HXR8204-QUAL likely represents a qualified or screened version of this wafer-level component.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The HXR6204 is a related but obsolete 4-channel 28Gb/s receiver with different environmental specifications (0 to 70°C).
