89HP0604QBZBNRGI8

Overview

The Renesas Electronics Corporation 89HP0604QBZBNRGI8 is a four-channel signal repeater and buffer designed for high-speed serial data applications. It supports data rates up to 6.25Gbps, making it suitable for XAUI and other demanding interfaces in computing, storage, and communications systems. The device is housed in a 36-VFQFPN package with dimensions of 4x7.5mm, featuring exposed pads for thermal management and grounding. It includes an I2C programming interface for configuration and diagnostic control. The component operates within commercial and industrial temperature ranges and incorporates advanced signal conditioning features to maintain signal integrity over extended trace lengths.

Feature Summary

• Four independent channels providing signal regeneration and buffering for high-speed serial links
• Integrated I2C interface enabling dynamic configuration, monitoring, and diagnostic capabilities
• Advanced signal conditioning circuitry optimized for maintaining eye diagram quality at high data rates
• Built-in power management features to reduce system energy consumption during idle or low-activity periods

Applications

• XAUI (10 Gigabit Attachment Unit Interface) signal extension in server backplanes
• High-speed storage area network (SAN) interconnects requiring signal integrity preservation
• Telecommunications equipment utilizing serial data transmission standards up to 6.25Gbps
• Computing infrastructure boards needing reliable signal re-driving across long copper traces

Procurement Notes

Verify the exact suffix BNRGI8 against official Renesas documentation, as standard listings often show BZBNRG. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements before procurement. Check for end-of-life notices or product discontinuance announcements from the manufacturer. Ensure supply chain sources provide genuine components with traceable origin records.

Selection Notes

Select this component when four-channel signal regeneration is required for protocols supporting up to 6.25Gbps. Compare pinout compatibility with existing board layouts due to the specific 36-VFQFPN package dimensions. Evaluate thermal performance needs given the exposed pad design. Consider alternative packages like CABGA if higher channel counts or different form factors are needed for the application.

Part Context

This part belongs to the 89HP0604 series of signal repeaters from Renesas, formerly IDT. It shares core functionality with variants such as 89HP0604XZBAB8 but differs in packaging and specific suffix configurations. The series is designed for high-performance signal integrity solutions in enterprise and telecom environments. Understanding the broader family helps in identifying compatible replacements or upgrades within the same product line.

Replacement Considerations

Direct substitutes include the 89HP0604XZBAB8 for CABGA packaging or the 89HP0604QBZBNRG for VFQFPN without the GI8 suffix. Verify functional equivalence regarding data rate support and I2C register maps. Check for any changes in pin assignments or thermal characteristics between original and replacement parts.
