9LRS3165BKLF

Overview

The Renesas 9LRS3165BKLF is a clock synthesizer and jitter cleaner designed for Intel CPU server applications. It features a single circuit with a 1:21 input-to-output ratio, generating up to 21 differential clock outputs from a crystal input. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 400MHz. Packaged in a 64-VFQFPN (9x9) exposed pad case, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Designed specifically for Intel CPU server main clock generation
• Integrates PLL functionality for precise clock synthesis
• Provides 21 differential clock outputs from a single crystal input
• Operates on a 3.135V to 3.465V supply voltage

Applications

• Intel CPU server main clock distribution
• High-performance computing systems requiring low-jitter clocking
• Server motherboards utilizing CK505-compatible architectures

Procurement Notes

Verify the specific ordering suffix BKLF against official Renesas documentation to confirm package type and temperature grade. As this component belongs to the Application Specific Clock/Timing category, ensure compatibility with existing system power rails and crystal specifications before procurement.

Selection Notes

Select the 9LRS3165BKLF when designing for Intel CPU servers requiring a 1:21 clock ratio. Ensure the design accommodates the 64-VFQFPN package dimensions and the specified 0°C to 70°C operating temperature range. Confirm that the system power supply remains stable within the 3.135V to 3.465V window.

Part Context

This part is categorized under Application Specific Clock/Timing devices by Renesas Electronics Corporation. It serves as a dedicated solution for server infrastructure, differing from general-purpose clock generators by its optimization for Intel CPU timing requirements and specific output configurations.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible alternatives within the same series. Verify if other suffixes such as BGILF or BKLF offer identical electrical characteristics with different packaging or environmental ratings.
