9DBL0252CKILF

Overview

The Renesas 9DBL0252CKILF is a PCIe zero-delay buffer supporting Gen1-4 Common Clocked systems. It features 3.3V operation with low-power HCSL outputs, eliminating external termination resistors through integrated 100Ω terminations. The device supports frequencies up to 200MHz and operates within a supply voltage range of 3.135V to 3.465V. It utilizes a 24-QFN (4x4) package and functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports PCIe Gen1 through Gen4 Common Clocked architectures
• Integrates 100Ω terminations to eliminate external resistors per output pair
• Provides low-power HCSL differential outputs for high-performance signaling

Applications

• PCI Express (PCIe) clock distribution in server platforms
• Common Clocked system timing synchronization
• High-speed peripheral interface clock buffering

Procurement Notes

Verify the specific suffix 'CKILF' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and voltage ranges. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes
