9LPRS525AGILF

Overview

The Renesas 9LPRS525AGILF 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 a maximum frequency of 400MHz and operates within a supply voltage range of 3.135V to 3.465V. It utilizes a PLL architecture and provides differential outputs while accepting a non-differential crystal input. The component is housed in a 56-TFSOP package with a width of 6.10mm and is rated for an operating temperature range of -40°C to 85°C.

Procurement Notes

Verify the specific suffix 'GLF' against official documentation to confirm lead-free status and RoHS compliance details. Confirm the package type matches the 56-TSSOP specification. Check current availability as this component may be subject to end-of-life notices or obsolescence. Ensure the supplier provides valid traceability for the manufacturing date code.

Selection Notes

Select this component when a dedicated solution for Intel CK505-compatible architectures is required. Ensure the design accommodates the 56-pin TSSOP footprint and the specified 3.135V-3.465V power rail. Verify that the system requires a single-ended crystal input and can utilize the provided differential outputs. Confirm thermal requirements align with the -40°C to 85°C industrial temperature grade.

Part Context

This part belongs to the 9LPRS525 family of clock synthesizers. It serves as a specialized timing solution for legacy Intel platform designs. The device integrates multiple output drivers into a single chip to reduce board space compared to discrete oscillator solutions. It is distinct from standard oscillators by offering programmable frequency multiplication via its internal PLL.

Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives. Generic clock generators may not match the specific output drive strengths or jitter specifications required for Intel CPU interfaces.
