9LPRS365BKLF

Overview

The Renesas 9LPRS365BKLF is a clock synthesizer and frequency multiplier designed for Intel CPU and PCI Express (PCIe) applications. It features a single circuit with a 1:21 input-to-output ratio, utilizing a crystal input to generate up to 21 differential clock outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies of 400MHz. Packaged in a 64-VFQFPN (9x9mm) with an exposed pad, it functions reliably between 0°C and 70°C.

Feature Summary

• Generates 21 differential clock outputs from a single crystal input
• Integrated PLL for precise frequency synthesis
• Optimized for Intel CPU and PCIe main clock generation
• Surface-mount 64-VFQFPN package

Applications

• Intel CPU system clocks
• PCI Express (PCIe) interface timing
• PC main clock distribution

Procurement Notes

This component has reached End-of-Life (EOL) status as per Product Change Notification dated May 7, 2019. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should initiate replacement strategies immediately due to the discontinuation.

Selection Notes

Select this part only if the design specifically requires a 1:21 multiplication ratio for Intel/PCIe architectures. Ensure the PCB layout accommodates the 64-VFQFPN footprint with an exposed thermal pad. Verify that the system power rail strictly maintains the 3.135V–3.465V range to meet electrical specifications.

Part Context

The 9LPRS365BKLF belongs to the 9LPRS365 series of clock synthesizers. It serves as a specialized timing solution for high-speed digital interfaces, replacing older jitter-cleaner designs in legacy PC motherboard architectures requiring multiple synchronized PCIe lanes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must consult Renesas for qualified alternatives or perform full redesign validation for cross-compatible devices.
