9LPRS365BGLFT

Overview

The Renesas Electronics Corporation 9LPRS365BGLFT is a clock synthesizer designed for Intel CPU and PCI Express (PCIe) applications. It operates with a single circuit, accepting a crystal input to generate up to 21 differential or single-ended clock outputs at frequencies reaching 400MHz. The device functions within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range of 0°C to 70°C. Packaged in a 64-TFSOP surface-mount case, it integrates a Phase-Locked Loop (PLL) for precise timing control.

Feature Summary

• Generates 21 output clocks from a single crystal input
• Supports maximum frequency of 400MHz
• Integrated PLL for jitter reduction
• Compatible with Intel CPU and PCIe architectures

Applications

• Intel CPU main clock generation
• PCI Express (PCIe) system timing
• Server motherboard clock distribution

Procurement Notes

Verify the specific package variant against project requirements, as the 9LPRS365 series includes both TSSOP and VFQFN options. Confirm availability status directly with authorized distributors, as this component may be subject to discontinuation notices or limited stock conditions. Ensure compliance with RoHS directives before integration.

Selection Notes

Select the 9LPRS365BGLFT when a 64-pin TSSOP footprint is required for Intel-based designs. Compare against the BKLFT variant if a smaller VFQFN package is preferred for space-constrained layouts. Verify that the 3.135V to 3.465V supply range aligns with the target board's power delivery network.

Part Context

This component belongs to the CK505 derivative family of clock generators. It serves as a timing solution for high-performance computing platforms requiring multiple synchronized clock signals derived from a single reference oscillator.

Replacement Considerations

The 9LPRS365BKLFT offers identical electrical specifications but utilizes a 64-VFQFPN package instead of the TSSOP form factor.
