9LP505-2HFLFT

Overview

The 9LP505-2HFLFT is a clock synthesizer designed for Intel desktop chipset applications, compliant with the CK505 Yellow Cover specification. It operates on a single 3.3V supply and features a 56-pin SSOP package. The device generates multiple differential and single-ended clock outputs required for system timing, including CPU, SRC, PCI, USB, and reference frequencies. It supports spread spectrum modulation to reduce electromagnetic interference (EMI) by up to -0.5% down spread. The component is rated for commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range. Confirm availability status as this part number may be subject to lifecycle changes or obsolescence. Ensure compatibility with existing board designs regarding pinout and electrical specifications before procurement.

Selection Notes

Select this component for designs requiring CK505-compatible clock signals for Intel-based architectures. Verify that the 0°C to +70°C commercial temperature range meets the environmental requirements of the target application. Ensure the 56-SSOP package footprint is compatible with the PCB layout constraints.

Part Context

This component belongs to the Renesas clock synthesizer family derived from the CK505 specification. It serves as a central timing solution for desktop computer motherboards, replacing discrete oscillator and buffer components with a single integrated circuit. It is distinct from higher-performance server-grade clock generators like the 9EPRS series.

Replacement Considerations

Direct replacements must match the CK505 specification and 56-pin SSOP package. Verify pin-to-pin compatibility and electrical parameters such as jitter and output drive strength. Check for updated revisions or alternative packages if the current stock is limited.
