ICS94211AFLF

Overview

The ICS94211AFLF is a programmable frequency generator designed for Intel CPU server applications. It features a single circuit with a 1:26 input-to-output ratio, supporting crystal inputs and clock outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 332MHz. Packaged in a 48-BSSOP (7.50mm width) surface-mount case, it functions within an operating temperature range of 0°C to 70°C. This component integrates PLL technology for precise frequency generation without differential signaling.

Procurement Notes

Verify the specific suffix 'AFLF' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with the required 3.135V–3.465V supply rail. Confirm that the 48-SSOP package aligns with PCB layout constraints. Check for any obsolescence notices or recommended replacements if available in public records.

Selection Notes

Select this component when designing for Intel CPU servers requiring a fixed 1:26 frequency multiplication from a crystal source. Ensure the system environment stays within 0°C to 70°C. Verify that non-differential clock outputs meet the load requirements of the downstream logic. Compare against other PhiClock series devices if lower jitter or wider temperature ranges are needed.

Part Context

This part belongs to the Renesas programmable clock generator family, specifically tailored for high-performance computing environments. It serves as a critical timing element in server infrastructure, providing stable clock signals derived from a crystal reference to synchronize CPU and chipset operations.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible alternatives within the same PhiClock series. Verify electrical parameters such as supply voltage and output drive strength before substituting.
