ICS9LPRS355CGLFT

Overview

The ICS9LPRS355CGLFT is a clock synthesizer manufactured by Renesas Electronics Corporation, designed for Intel CPU and PCI Express (PCIe) applications. It operates on a single 3.3V supply voltage and features a crystal input to generate precise clock outputs. The device is housed in a 64-TSSOP surface-mount package with dimensions of 0.240 inches (6.10mm) width. It functions as a CK505 derivative, providing essential timing signals for system components within an operating temperature range of 0°C to 70°C.

Feature Summary

• Designed specifically for Intel CPU and PCI Express (PCIe) architectures
• Operates at a core voltage of 3.3V with crystal input configuration
• Packaged in a 64-TSSOP surface-mount case for compact integration

Applications

• Intel CPU chipset timing solutions
• PCI Express (PCIe) interface clock generation
• Desktop motherboard main clock distribution

Procurement Notes

Verify the specific suffix 'CGLFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with existing board layouts requiring 64-pin TSSOP footprints. Confirm availability status as this component family may have discontinued variants.

Selection Notes

Select this component when a CK505-compatible clock synthesizer is required for Intel-based platforms. Ensure the design supports a 3.3V power rail and utilizes a crystal oscillator input. Verify that the 64-TSSOP package dimensions fit the target PCB space constraints and thermal requirements for commercial temperature ranges.

Part Context

This part belongs to the Renesas clock generator portfolio, serving as a derivative of the industry-standard CK505 specification. It replaces legacy timing solutions in desktop computing systems, providing integrated jitter cleaning and frequency synthesis for PCIe and CPU buses without requiring external PLL components.
