GX66473-HIU

Overview

The GX66473-HIU is a quad-channel linear differential driver designed for high-speed optical transmitter applications. It supports data rates up to 64 Gbps per channel, providing four independent channels within a single small form factor (SFF) surface-mount device package. The component features differential inputs and single-ended outputs, optimized for low-power operation in metro optical networking environments. Operating temperature range is specified from -5°C to 85°C. This module requires wafer-level integration and is currently classified as an End-of-Life product with restricted supply availability.

Procurement Notes

Verify current availability status as the GX66473-HIU is listed as an End-of-Life product. Restricted supply conditions may apply. Confirm compatibility with existing design-in requirements before procurement. Check official Renesas documentation for final discontinuance notifications and last-time-buy information. Ensure environmental compliance data aligns with project specifications.

Selection Notes

Select this component for designs requiring a compact, low-power solution for multi-channel optical transmission. The SFF package aids in space-constrained layouts. Verify that the 64 Gbps speed meets system bandwidth requirements. Consider the End-of-Life status when planning long-term production lifecycles. Evaluate thermal performance within the specified -5°C to 85°C operating range.

Part Context

The GX66473 series represents Renesas' high-performance linear driver family for optical communications. The HIU suffix denotes specific packaging or variant characteristics within the SFF surface-mount category. This part integrates four channels into a single module, reducing board space compared to discrete solutions. It targets next-generation metro optical infrastructure demanding high density and energy efficiency.

Replacement Considerations

No public confirmed substitute part numbers are available. As an End-of-Life product, direct replacements must be evaluated based on pinout and electrical parameter compatibility. Consult Renesas for potential obsolescence management options or newer generation alternatives.
