9LPRS477DKLF

Overview

The 9LPRS477DKLF is a clock generator from Renesas Electronics Corporation designed for AMD CPU and SATA applications. It features an integrated PLL and accepts crystal input to generate clock outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports both differential and single-ended output configurations. It is rated for an operating temperature range of 0°C to 70°C (TA) and is housed in a 64-VFQFN exposed pad package, specifically the 64-VFQFPN (9x9) supplier device package.

Feature Summary

• Integrated PLL for clock generation
• Supports AMD CPU and SATA main purposes
• Crystal input with mixed differential/single-ended outputs
• Operates at 3.135V ~ 3.465V supply voltage

Applications

• AMD CPU systems
• SATA interface designs

Procurement Notes

Verify the specific suffix DKLF against official Renesas documentation to confirm exact pinout, packaging variant, and compliance status. Ensure the 64-VFQFPN (9x9) package dimensions match the design footprint requirements. Confirm the commercial temperature grade (0°C to 70°C) aligns with the target application environment constraints.

Selection Notes

Select this component when designing for AMD chipset or SATA controller clocking needs requiring a single-circuit PLL solution. Verify that the crystal input requirement fits the system oscillator strategy. Ensure the 3.135V-3.465V supply rail is stable and compatible with the rest of the logic family. Check if the commercial temperature range meets the deployment conditions.

Part Context

This part belongs to the Application Specific Clock/Timing category. It is distinct from general-purpose oscillators by its dedicated support for AMD CPU and SATA architectures. The 64-pin VFQFN package allows for compact surface-mount integration in high-density motherboard or storage controller designs.

Replacement Considerations

Consult Renesas official substitution guides for direct equivalents. Verify compatibility of output drive strength and jitter specifications if replacing with other clock generators in the same timing portfolio.
