9LPRS502SGLF

Overview

The Renesas 9LPRS502SGLF is a clock generator IC based on the CK505 architecture, designed for Intel and PCI Express applications. It features an integrated voltage regulator (VREG) and accepts crystal input to produce differential or single-ended clock outputs. The device supports a 1:19 frequency ratio with a maximum output frequency of 400MHz. It operates within a supply voltage range of 3.135V to 3.465V and functions at temperatures between 0°C and 70°C. The component is housed in a 56-TSSOP surface-mount package.

Feature Summary

• Integrated CK505 VREG architecture for simplified power management
• Supports 1:19 frequency multiplication from crystal input
• Capable of generating differential or single-ended clock outputs up to 400MHz
• Optimized for Intel and PCI Express system requirements

Applications

• Intel platform clock generation
• PCI Express (PCIe) interface timing
• System clock distribution networks

Procurement Notes

Verify the specific ordering suffix 'SGLF' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Ensure the 56-TSSOP footprint matches the target PCB design. Confirm that the 3.135V–3.465V supply range aligns with the system's power rails before procurement.

Selection Notes

Select this component when a dedicated clock generator with an internal regulator is required for PCIe or Intel architectures. The 1:19 ratio suits applications needing high-frequency outputs from lower-frequency crystals. Verify thermal performance within the 0°C to 70°C operating range for the intended environment.

Part Context

This part belongs to the Renesas clock timing family, specifically utilizing the CK505 core technology. It serves as a specialized solution for high-speed serial interfaces like PCIe, replacing discrete oscillator and buffer combinations with a single integrated circuit.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible alternatives within the CK505 series. Verify electrical parameters such as jitter specifications and output drive strength when considering cross-model substitutes.
