9LP505-1HGLFT

Overview

The Renesas 9LP505-1HGLFT is a clock generator IC designed for Intel chipset applications, functioning as a CK505 derivative. It accepts a crystal input and provides up to 22 outputs with frequencies reaching 400MHz. The device operates on a 3.135V to 3.465V supply within an industrial temperature range of 0°C to 70°C. Key features include integrated voltage regulation and series resistors on differential outputs. It supports PCIe Gen1 compliance and spread spectrum modulation for EMI reduction. The component is housed in a 64-pin TSSOP package.

Feature Summary

• CK505 compatible clock generator with integrated voltage regulator
• Supports PCIe Gen1 specifications with low jitter performance
• Integrated series resistors on differential outputs
• Spread spectrum modulation capability for EMI reduction

Applications

• Intel desktop chipset clock generation
• PCI Express (PCIe) interface timing
• Industrial embedded systems requiring CK505 compatibility

Procurement Notes

Verify the specific suffix '1HGLFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure the source document explicitly lists this part number as active or available, as similar CK505 derivatives may have varying lifecycle statuses. Cross-reference the 64-TSSOP package dimensions with the datasheet to ensure mechanical compatibility.

Selection Notes

Select this component when a CK505-compatible solution is required for Intel-based designs. Verify that the 0°C to 70°C operating temperature range meets the system's environmental requirements. Confirm that the single-ended crystal input and differential HCSL/LVPECL output signaling match the target chipset's clocking architecture. Check if the integrated voltage regulator simplifies the power design compared to external regulator solutions.

Part Context

This part belongs to the family of CK505 derivative clock generators used primarily in PC and server platforms. It serves as a direct replacement or alternative for standard Intel CK505 clock synthesizers, offering similar pinouts and functionality while potentially providing enhanced integration such as built-in voltage regulation and series termination resistors.
