932S421BGLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 932S421BGLFT is a clock frequency synthesizer IC designed for Intel CPU server applications. It features a single circuit with a 1:19 input-to-output ratio and supports crystal inputs to generate HCSL outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 400MHz. It utilizes an internal PLL and is housed in a 56-TFSOP (56-TSSOP) package with a width of 6.10mm. The component functions across an operating temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• Operates at maximum frequencies of 400MHz with a 3.135V to 3.465V supply
• Available in a 56-lead TFSOP surface-mount package

Application Specific Clock/Timing Applications

• Intel CPU server main clock generation
• System timing distribution for high-performance computing platforms

Application Specific Clock/Timing Procurement Notes

The 932S421BGLFT has reached end-of-life status, with discontinuation notices issued by the manufacturer in early 2022. Verification of current availability requires checking distributor stock lists for remaining inventory or obsolete lots. Designers should confirm RoHS3 compliance and MSL Level 1 ratings through official datasheets before procurement attempts.

Application Specific Clock/Timing Selection Notes

This component is specifically engineered for Intel server architectures requiring precise clock synthesis. Selection must account for the fixed 56-TFSOP footprint and the requirement for a crystal input source. Engineers should verify that the 400MHz maximum frequency and HCSL output swing meet the specific load requirements of the target Intel CPU platform.

Application Specific Clock/Timing Part Context

The 932S421BGLFT belongs to the Renesas 932S421 series of clock synthesizers. It shares the base product number 932S421 but is distinguished by its specific packaging suffix and performance characteristics tailored for server-grade timing solutions within the broader Renesas portfolio of programmable clock devices.

Application Specific Clock/Timing Replacement Considerations

The 932SQ420DGLFT is listed as a substitute part by distributors. This alternative offers a 64-TFSOP package and a maximum frequency of 146.7MHz. Pinout compatibility and electrical parameter differences require careful evaluation against the original design specifications.
