9LPR502HGLF

Overview

The ICS9LPR502HGLF is a PCI Express (PCIe) clock generator and frequency synthesizer manufactured by Renesas Electronics. Designed for Intel CK505 platforms, this integrated circuit provides a single output with a maximum frequency of 400MHz. It utilizes a crystal input and features an internal Phase-Locked Loop (PLL) to generate precise timing signals. The device operates within a supply voltage range of 3.135V to 3.465V and supports a 1:19 input-to-output ratio. It is housed in a 56-TSSOP surface-mount package and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Generates high-precision PCIe clock signals using an internal PLL for low-jitter performance
• Supports Intel CK505 platform requirements with dedicated frequency synthesis capabilities
• Accepts crystal input and provides flexible output ratios for system timing needs

Applications

• Intel CK505 chipset-based motherboard designs
• PCI Express interface clock generation
• Server and workstation mainboard timing circuits

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS3 compliance status and check current lifecycle status, as availability may be limited. Ensure the specific suffix matches the required package and temperature grade for your design implementation.

Selection Notes

Select this component when designing for Intel CK505 architectures requiring a dedicated PCIe clock source. Ensure the 56-TSSOP package fits the PCB layout constraints. Verify that the 3.3V nominal supply voltage aligns with the system power rails and that the 0°C to 70°C operating range meets environmental specifications.

Part Context

This part belongs to the ICS9LPR502 family of application-specific clock generators. It is closely related to variants like the ICS9LPR502SGLF, differing primarily in packaging and specific suffix designations. These components are integral to legacy Intel chipset designs, providing essential timing references for high-speed serial interfaces.
