9ZXL1252EKILF

Overview

The Renesas 9ZXL1252EKILF is a clock buffer within the 9ZML1252E series, designed for low phase noise applications. It features one differential input and twelve LP-HCSL outputs, supporting frequencies up to 400 MHz. The device operates on a single 3.3V supply (3.135V to 3.465V) and consumes approximately 481 mW of power. Housed in a 64-pin VFQFPN package measuring 9.0 x 9.0 mm with a 0.5 mm pitch, it functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• 1:12 fan-out ratio with differential input and LP-HCSL outputs
• Supports input frequencies from 1 MHz to 400 MHz
• Low power consumption of 481 mW typical
• Industrial operating temperature range (-40°C to +85°C)

Applications

• Servers and high-performance computing systems
• NVMe storage controllers
• Networking accelerators
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for Product Change Notifications (PCNs) regarding packaging or assembly site updates before procurement. Ensure handling procedures account for Moisture Sensitivity Level 3 requirements.

Selection Notes

Select this component when a 1:12 distribution ratio with LP-HCSL signaling is required for PCIe or QPI interfaces. Compare against the 9ZXL1251EKILFT variant if reel packaging is preferred over trays. Verify that the 400 MHz maximum frequency meets system timing requirements. Ensure the 3.3V supply voltage aligns with the target board design.

Part Context

This part belongs to the 9ZML/9ZXL family of clock buffers by Renesas Electronics. These devices are engineered for high-speed data transmission standards, specifically targeting Intel QPI and PCI Express architectures. The 9ZXL1252EKILF serves as a specific derivative optimized for low-power clock distribution in dense server environments.

Replacement Considerations

The 9ZXL1252EKILFT is a functional equivalent differing primarily in tape-and-reel packaging instead of tray. Other variants like the 9ZXL1231EKILF offer different output counts or signaling types and require schematic verification.
