932SQ420DGLF

Application Specific Clock/Timing Overview

The Renesas 932SQ420DGLF is an Intel Romley clock synthesizer IC designed for server applications. It features a single PLL circuit with a crystal input and HCSL differential outputs. The device generates a maximum frequency of 146.7MHz with a 1:19 input-to-output ratio. It operates on a supply voltage between 3.135V and 3.465V within a commercial temperature range of 0°C to 70°C. The component is housed in a 64-TFSOP package, measuring 6.10mm in width.

Application Specific Clock/Timing Feature Summary

• Intel Romley architecture compatibility
• Single PLL with 1:19 output ratio
• HCSL differential signaling outputs
• 64-TFSOP surface mount package

Application Specific Clock/Timing Applications

• Intel Romley platform servers
• CPU clock generation systems
• Server motherboard timing circuits

Application Specific Clock/Timing Procurement Notes

Verify the RoHS3 compliance status and MSL rating (Level 1) before integration. Confirm the specific suffix 'GLFT' indicates lead-free and tape-and-reel packaging as per distributor listings. Check for any Product Change Notices regarding assembly site or labeling updates that may affect part identification.

Application Specific Clock/Timing Selection Notes

Select this component for designs requiring strict adherence to Intel Romley clocking specifications. Ensure the design supports the 3.135V to 3.465V supply range. Verify that the 64-pin TFSOP footprint matches the PCB layout constraints. Consider the 146.7MHz maximum frequency limit when determining system clock requirements.

Application Specific Clock/Timing Part Context

This part belongs to the 932SQ series of clock generators optimized for Intel server processors. It serves as a critical timing element for CPU synchronization. The device replaces earlier generations of clock synthesizers used in Romley-based architectures, providing standardized HCSL outputs for low-power high-speed logic interfaces.

Application Specific Clock/Timing Replacement Considerations

The 932S421BGLFT is listed as a substitute option, though it operates at a higher frequency (400MHz) and uses a 56-TSSOP package. Verify pinout compatibility and electrical parameter alignment before substitution.
