9DBL0841BKILF

Overview

The 9DBL0841BKILF is a zero-delay buffer integrated circuit designed for PCI Express applications, manufactured by Renesas Electronics Corporation. It features a single input-to-eight output configuration with differential HCSL signaling on both input and output sides. The device operates at a maximum frequency of 200MHz and requires a supply voltage between 3.135V and 3.465V. Packaged in a 48-VFQFN (6x6mm) format with an exposed pad, it supports surface-mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• PCIe Zero-Delay Buffer: Supports zero-delay buffer mode for precise clock alignment.
• High-Speed Performance: Operates up to 200MHz with differential HCSL I/O.
• 1:8 Distribution Ratio: Splits one input signal into eight synchronized outputs.
• Compact Packaging: Available in a 48-pin VFQFPN (6x6mm) package.

Applications

• PCI Express Riser Cards
• NVMe Storage Systems
• Networking Accelerators

Procurement Notes

Verify the component status as this specific part number may be discontinued or superseded by newer revisions such as the 9DBL0841CKILFT. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) requirements during procurement. Ensure the ordering suffix matches the required tape-and-reel quantity specifications.

Selection Notes

Select this component when a PCIe system requires a single-source clock distributed to eight endpoints with minimal skew. Ensure the design accommodates the 3.3V nominal supply voltage and the thermal dissipation needs of the 48-VFQFN package. Verify that the input source provides a compatible HCSL signal suitable for zero-delay buffering.

Part Context

This device belongs to the Renesas 9DBL series of PCIe clock buffers. It serves as a critical timing element in high-speed serial link architectures, ensuring signal integrity across multiple PCIe lanes. The part is often used in conjunction with main clock generators like the CK410B+ or CK505 families to distribute reference clocks.

Replacement Considerations

The 9DBL0841CKILFT is identified as a replacement alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any packaging or marking changes associated with the updated suffix.
