9LPRS525AGLF

Overview

The Renesas 9LPRS525AGLF is a clock and frequency synthesizer IC designed for Intel CPU and PCI Express (PCIe) applications. It features a single circuit with a 1:19 input-to-output ratio, driven by an external crystal. The device supports maximum frequencies of 400MHz and operates within a supply voltage range of 3.135V to 3.465V. Packaged in a 56-TFSOP (56-TSSOP) surface-mount case, it functions at temperatures between 0°C and 70°C. The component integrates a PLL and provides differential outputs while accepting non-differential inputs.

Feature Summary

• Designed for Intel CPU and PCIe chipset synchronization
• Single circuit configuration with 1:19 input-to-output ratio
• Supports output frequencies up to 400MHz
• Operates on 3.135V to 3.465V supply voltage

Applications

• Intel desktop chipset clock generation
• PCI Express interface timing
• CPU clock distribution systems

Procurement Notes

Verify the specific ordering suffix 'GLF' against manufacturer documentation to confirm lead-free status and RoHS compliance details. Confirm package dimensions match the 56-TFSOP specification. Check current product lifecycle status as this series may have end-of-life notifications or obsolescence warnings from the manufacturer.

Selection Notes

Select this component when a single-channel synthesizer for Intel architecture is required. Ensure the design accommodates the 3.135V–3.465V supply range. Verify that the 56-pin TSSOP footprint fits the PCB layout constraints. Confirm that the 0°C to 70°C operating temperature range meets the system environmental requirements.

Part Context

This part belongs to the 9LPRS525 family of clock synthesizers. It serves as a derivative solution for embedded systems requiring precise timing for legacy Intel platforms. The component replaces older discrete timing solutions by integrating multiple output drivers into a single chip.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas family. Verify if newer generations support the same 400MHz frequency and PCIe specifications. Ensure any substitute maintains the 56-TSSOP package outline.
