932S421BGLF-INT

Application Specific Clock/Timing Overview

The Renesas 932S421BGLF-INT 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, generating up to 19 outputs from one crystal input. The device operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 400MHz. Outputs utilize HCSL signaling. It is housed in a 56-TFSOP (56-TSSOP) package with a width of 6.10mm. The component includes an internal PLL and functions as a differential output generator.

Application Specific Clock/Timing Procurement Notes

The 932S421BGLFT variant is listed as obsolete with a discontinuation notice dated January 19, 2022. Verification of the specific -INT suffix functionality is required against official datasheets, as standard suffixes typically denote packaging or temperature ranges rather than functional changes. Current availability status should be confirmed through authorized channels given the EOL designation.

Application Specific Clock/Timing Selection Notes

Select this component for Intel-based server architectures requiring a single-input, multi-output clock distribution solution. Ensure the design accommodates the 56-pin TFSOP footprint and the 3.135V–3.465V power supply constraints. Verify that the 400MHz maximum frequency meets the target bus speed requirements and that HCSL output compatibility exists with downstream receivers.

Application Specific Clock/Timing Part Context

This part belongs to the Renesas 932S421 series of clock generators. It is specifically optimized for high-performance computing environments, particularly those utilizing Intel processors. The device integrates phase-locked loop (PLL) technology to synthesize frequencies from a single crystal reference, reducing board space compared to discrete solutions.
