9DBL0851CKILFT

Overview

The 9DBL0851CKILFT is a clock buffer manufactured by Renesas Electronics, designed for PCI Express applications. It features an 8-output configuration with zero delay (ZD) architecture and an output impedance of 85 ohms. The device operates on a single 3.3V power supply within the range of 3.135V to 3.465V. It supports input frequencies up to 200MHz and functions across an industrial temperature range of -40°C to +85°C. The component utilizes HCSL input and output signaling standards.

Feature Summary

• Eight differential outputs with 85-ohm termination
• Zero-delay feedback loop for minimal jitter
• HCSL compatible input and output drivers
• Industrial operating temperature range (-40°C to +85°C)

Applications

• PCI Express clock distribution networks
• High-speed digital system timing synchronization

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm moisture sensitivity level (MSL) handling requirements during storage and assembly. Ensure the specific suffix matches design specifications as package or revision changes may affect mechanical fit without altering electrical function.

Selection Notes

Select this component when an 8-channel zero-delay buffer with 85-ohm output impedance is required for PCIe designs. Verify that the 200MHz maximum frequency meets system clock requirements. Compare against other series members like the 9DBL0841 if different output counts or impedances are needed.

Part Context

This part belongs to the 9DBL0851 series of clock buffers. It shares architectural similarities with other devices in the Renesas PCIe buffer family but is distinguished by its specific 8-output count and 85-ohm termination characteristics tailored for high-speed serial link interfaces.

Replacement Considerations

Direct substitutes within the same series include variants with different output counts or impedances. Cross-series replacements require verification of pin compatibility and electrical parameter alignment.
