9LPRS501PGLF

Overview

The 9LPRS501PGLF is a clock generator IC designed for Intel CK505 and PCI Express (PCIe) applications. It operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 400MHz. The device features a 1:22 input-to-output ratio with differential outputs, utilizing a TSSOP-64 package. It includes an integrated voltage regulator and series resistors on differential outputs, eliminating the need for external pass transistors. The component supports spread spectrum modulation and is compliant with PCIe Gen 1 standards.

Feature Summary

• Fully integrated voltage regulator without requiring external pass transistors
• Integrated series resistors on differential outputs with Zo=50Ω
• Supports spread spectrum modulation with a default 0.5% down spread
• Compliant with Intel CK505 specifications and PCIe Gen 1 requirements

Applications

• Intel CK505 compliant clock systems
• PCI Express (PCIe) Gen 1 clock generation
• Server and workstation motherboard timing

Procurement Notes

Verify the specific ordering suffix 'PGLF' against official Renesas documentation to confirm package type and tape/reel configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to procurement. Check for end-of-life notices or alternative part recommendations from the manufacturer.

Selection Notes

Select this component for designs requiring a CK505-compatible clock source with integrated power regulation. Ensure the system design accommodates the 64-TSSOP package dimensions. Verify that the required output frequencies align with the device's maximum 400MHz capability and that the 14.318MHz crystal input is supported by the system oscillator.

Part Context

This part belongs to the 9LPRS501 family of clock generators. It is manufactured by Renesas Electronics Corporation, which acquired Integrated Device Technology (IDT). The device serves as a specialized timing solution for high-performance computing platforms requiring precise clock distribution for CPU and peripheral interfaces.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible substitutes within the 9LPRS501 series. Verify if variants like 9LPRS501SGLFT offer identical electrical characteristics and packaging for drop-in replacement.
