9LPR501SGLF

Overview

The Renesas 9LPR501SGLF is a dedicated clock and frequency synthesizer IC designed for Intel CK505 and PCI Express (PCIe) applications. It features a single circuit with a crystal input and differential clock outputs, operating at a maximum frequency of 400MHz. The device utilizes an internal PLL and supports a 1:17 input-to-output ratio. It functions within a supply voltage range of 3.135V to 3.465V and is rated for temperatures between 0°C and 70°C. Housed in a 64-TFSOP surface-mount package, it provides precise timing signals for high-speed digital interfaces.

Feature Summary

• Designed specifically for Intel CK505 and PCIe clocking requirements
• Integrates a Phase-Locked Loop (PLL) for frequency synthesis
• Supports differential output signaling for noise immunity
• Operates on a 3.135V to 3.465V power supply

Applications

• PCI Express (PCIe) system clock generation
• Intel CK505 chipset timing solutions
• High-speed digital interface synchronization

Procurement Notes

Verify the exact part number suffix against official Renesas documentation, as variations may exist between 9LPRS501 and 9LPR501. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to procurement. Check for end-of-life notices or last-time-buy notifications from the manufacturer to ensure long-term availability for production planning.

Selection Notes

Select this component when a fixed-ratio 1:17 clock divider is required for PCIe or CK505 architectures. Ensure the design accommodates the 64-TSSOP footprint and 3.3V nominal supply constraints. Verify that the 0°C to 70°C commercial temperature range meets the environmental specifications of the target application board.

Part Context

This component belongs to the Renesas clock generator family targeting legacy and specific industrial PCIe implementations. It serves as a replacement or alternative for discrete clocking solutions in systems requiring stable, low-jitter reference clocks for data transmission interfaces compliant with Intel platform specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or pin-compatible alternatives if this specific SKU is discontinued.
