9ZXL1252EKILFT

Overview

The Renesas 9ZXL1252EKILFT is a clock buffer within the 9ZXL series, designed for high-performance computing applications. It features one differential input and twelve low-power HCSL (LP-HCSL) outputs, supporting frequencies up to 400 MHz. The device operates on a single 3.3V supply voltage with a range of 3.135 V to 3.465 V. Packaged in a 64-pin VFQFPN (9x9 mm) surface-mount housing, it functions as a derivative of the DB1200ZL component. The IC is rated for an operating temperature range from -40°C to +85°C and includes spread spectrum capability.

Feature Summary

• 1:12 Input-to-Output Ratio
• Differential Input with LP-HCSL Outputs
• Maximum Frequency of 400 MHz
• Spread Spectrum Input Support

Applications

• Servers and High-Performance Computing
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control Systems

Procurement Notes

Verify the specific suffix EKILFT against the official datasheet to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory details may vary by production batch. Ensure the ordering quantity aligns with the standard reel packaging specifications provided in the product documentation.

Selection Notes

Select this component when a 1:12 distribution ratio is required for PCIe Gen 3/4 or Intel QPI architectures. The LP-HCSL output type is suitable for board-level clock distribution where power consumption is a constraint. Verify that the 400 MHz maximum frequency meets the system's timing requirements and that the 64-VFQFPN package fits the available PCB footprint.

Part Context

This part belongs to the 9ZXL family of clock buffers derived from the DB1200ZL specification. It serves as a specialized solution for distributing reference clocks in complex digital systems. The 'E' suffix typically denotes enhanced performance or specific manufacturing revisions within the Renesas portfolio, distinguishing it from earlier generation variants.

Replacement Considerations

Direct pin-compatible substitutes are not explicitly listed in the provided data. Evaluate other members of the 9ZXL series, such as the 9ZXL1232E or 9ZML1252E, if different input/output signaling types or lower frequency requirements are acceptable. Always verify electrical parameters against the target application before substitution.
