9LPR501HGLF

Overview

The 9LPR501HGLF is an application-specific clock and timing integrated circuit manufactured by Renesas Electronics Corporation. Designed primarily for Intel CK505 and PCI Express (PCIe) systems, this device functions as a clock generator with a maximum frequency of 400MHz. It features a single circuit configuration with a 1:22 input-to-output ratio. The component utilizes a crystal input and provides differential clock outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports surface mount installation in a 64-TFSOP package.

Feature Summary

• Supports PCIe and Intel CK505 specific timing requirements
• Generates high-frequency clock signals up to 400MHz
• Integrates fully integrated voltage regulation capabilities

Applications

• PCI Express system clock generation
• Intel CK505 platform timing
• High-speed digital interface synchronization

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the 64-TFSOP package dimensions match the target PCB footprint. Ensure the 3.135V to 3.465V supply voltage aligns with the system design. Check for RoHS3 compliance if required by environmental regulations. Evaluate alternative components due to end-of-life status.

Selection Notes

Select this component when designing for Intel CK505 or PCIe architectures requiring a 400MHz clock source. The 1:22 output ratio suits complex bus topologies. Verify compatibility with crystal oscillators for the input stage. Consider the 64-pin form factor for board space constraints. Ensure thermal management supports the 0°C to 70°C operating range.

Part Context

This part belongs to the 9LPRS501 series of clock generators. It shares functional similarities with the 9LPRS501SGLFT but differs in packaging and suffix designation. The series targets high-performance computing and server applications. Renesas Electronics developed these ICs to meet strict timing jitter specifications for modern data interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements must be sourced from manufacturer cross-reference lists. Designers should evaluate newer Renesas clock generator families for long-term availability.
