9LPRS501SKLF

Overview

The Renesas 9LPRS501SKLF is a clock frequency synthesizer IC compliant with the Intel CK505 specification, designed for PCI Express (PCIe) applications. It features a single PLL circuit with one input and twenty-two outputs, supporting a maximum frequency of 400MHz. The device operates on a supply voltage range of 3.135V to 3.465V and accepts a crystal input. It provides differential output signaling in a 64-VFQFPN package with an exposed pad, suitable for surface mount installation within an operating temperature range of 0°C to 70°C.

Feature Summary

• Intel CK505 compliant architecture for PCIe system clock generation
• 1:22 input-to-output ratio with differential output capability
• Maximum output frequency of 400MHz driven by external crystal
• Operates at 3.135V ~ 3.465V supply voltage

Applications

• PCI Express (PCIe) clock distribution systems
• Intel chipset-based motherboard designs
• High-speed digital interface timing solutions

Procurement Notes

Verify the specific suffix 'SKLF' against official Renesas documentation to confirm package details and compliance status. Confirm end-of-life or last-time-buy status through authorized distributors, as availability may be limited. Ensure the 64-VFQFPN footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this component when an Intel CK505-compatible clock solution is required for PCIe architectures. Ensure the design supports the specified 3.135V to 3.465V supply range and utilizes an external crystal oscillator. Verify that the 64-VFQFPN package dimensions are compatible with the assembly process and thermal management constraints of the application.

Part Context

This part belongs to the 9LPRS series of clock synthesizers from Renesas Electronics. It serves as a specialized timing generator for complex digital systems requiring multiple synchronized clock signals derived from a single reference source, specifically targeting legacy and current Intel platform standards.

Replacement Considerations

Check for direct pin-to-pin replacements within the 9LPRS family or newer Renesas clock generators that maintain CK505 compatibility. Verify electrical parameters such as jitter performance and output drive strength against the original design specifications.
