9LRS3187BKLFT

Overview

The Renesas 9LRS3187BKLFT is a programmable timing controller within the TCH series, designed for Intel CPU and Timing Control Hub applications. It features one circuit with a 1:7 input-to-output ratio, accepting crystal inputs to generate clock outputs. The device supports differential outputs but lacks differential input capability. It operates at a maximum frequency of 133.33MHz with an integrated PLL. Power supply requirements range from 3.135V to 3.465V, and it functions within a commercial temperature range of 0°C to 70°C. The component is housed in a 32-VFQFPN (5x5) surface-mount package.

Feature Summary

• Integrated PLL for programmable clock generation
• 1:7 Input/Output Ratio supporting multiple output clocks
• Differential Output Capability
• Crystal Input Interface

Applications

• Intel CPU Clock Distribution
• Timing Control Hub Systems

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the 32-VFQFPN package dimensions match the target PCB footprint design constraints.

Selection Notes

Select this component when a single crystal input must drive seven distinct clock outputs for Intel-based architectures. Verify that the required output frequencies fall within the 133.33MHz maximum limit. Ensure the system power rail aligns with the 3.135V to 3.465V operating range and that the 0°C to 70°C temperature rating meets environmental requirements.

Part Context

This part belongs to the TCH™ series of timing controllers manufactured by Renesas Electronics Corporation. It is specifically engineered for high-performance computing platforms requiring precise clock synchronization for Intel processors and associated chipset components.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic clock generators may not support the specific TCH programming interface or Intel-specific timing requirements.
