9LPRS501SKLFT

Overview

The Renesas 9LPRS501SKLFT is a clock/frequency synthesizer IC designed for Intel CK505 and PCI Express (PCIe) applications. It features a single circuit with a 1:22 input-to-output ratio, generating outputs up to 400MHz from a crystal input. The device operates on a supply voltage of 3.135V to 3.465V within an operating temperature range of 0°C to 70°C. Packaged in a 64-VFQFPN (9x9mm) surface-mount case with an exposed pad, it integrates PLL functionality for precise timing generation.

Feature Summary

• Intel CK505 derivative supporting PCIe clock requirements
• Integrated Voltage Regulator (VREG) and series resistor
• Single-ended and differential output capabilities
• Crystal input with 1:22 frequency ratio

Applications

• Intel CK505 chipset clock generation
• PCI Express (PCIe) system timing
• Desktop motherboard clock distribution
