9LP525BF-2LFT

Overview

The Renesas 9LP525BF-2LFT is a clock generator designed for Intel CPU server applications, compliant with the CK505 specification. It features a single circuit with crystal input and multiple differential clock outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 100MHz. Packaged in a 56-BSSOP (7.50mm width) surface-mount case, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Compliant with Intel CK505 Yellow Cover specification
• Single PLL circuit with 1:19 frequency ratio
• Differential output signaling capabilities
• Crystal input interface

Applications

• Intel CPU Servers
• Embedded Systems Clocking

Procurement Notes

Verify the specific suffix '2LFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure the 56-BSSOP package dimensions match the required PCB footprint. Confirm the commercial temperature grade (0°C to 70°C) aligns with system thermal requirements.

Selection Notes

Select this component for designs requiring CK505 compatibility. Verify that the 100MHz maximum frequency meets system timing needs. Ensure the 3.135V–3.465V supply voltage is stable. Check if the 56-pin SSOP package fits the available board space compared to alternative TSSOP or QFN packages.

Part Context

This part belongs to the Renesas clock synthesizer family targeting Intel architecture servers. It serves as a derivative solution for generating precise clock signals for CPUs and memory controllers, replacing older discrete timing components with a single integrated chip.

Replacement Considerations

Check for direct pin-to-pin replacements within the Renesas portfolio that offer extended temperature ranges or updated packaging options. Verify electrical compatibility with existing system power rails and load requirements before substitution.
