9DBL0841CKILFT

Overview

The 9DBL0841CKILFT is a zero-delay fanout buffer manufactured by Renesas Electronics Corporation, designed for PCI Express (PCIe) clock distribution. It features a single differential HCSL input and eight differential LP-HCSL outputs, operating at frequencies up to 200MHz. The device functions within a supply voltage range of 3.135V to 3.465V and supports an industrial temperature range of -40°C to 85°C. Packaged in a 48-VFQFN (6x6mm) with exposed pad, it integrates a PLL for jitter attenuation and is RoHS3 compliant.

Feature Summary

• Zero-delay architecture with integrated PLL for PCIe clock applications
• 1:8 differential input-to-output ratio (HCSL to LP-HCSL)
• Maximum operating frequency of 200MHz
• 48-VFQFN package with exposed thermal pad

Applications

• PCI Express Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

Verify component status as the predecessor 9DBL0841BKILFT is marked obsolete. Confirm current availability through authorized distributors. Ensure ordering suffixes match required packaging formats such as tape and reel or cut tape. Validate RoHS3 compliance and moisture sensitivity level (MSL 3) requirements for assembly processes.

Selection Notes

Select this model when eight low-power HCSL outputs are required from a single HCSL source. Ensure the design accommodates the 3.3V nominal supply voltage tolerance. Verify that the 48-VFQFN footprint fits the PCB layout constraints. Consider the 200MHz maximum frequency limit against system clock requirements.

Part Context

This component belongs to the 9DBL0841 family of PCIe clock buffers. It serves as a successor or alternative to the 9DBL0841BKILFT. The series is optimized for high-speed serial interface timing integrity, providing signal buffering and jitter cleaning for downstream PCIe endpoints.

Replacement Considerations

The 9DBL0841BKILFT is listed as obsolete with this part as a recommended replacement. Verify pin compatibility and electrical specifications before substitution. No other direct cross-model substitutes are documented in the provided data.
