ICS951464AGLFT

Overview

The ICS951464AGLFT is a system clock generator designed for AMD CPU and graphics applications. It features a single PLL circuit with a 1:16 input-to-output frequency ratio, supporting maximum output frequencies up to 280MHz. The device accepts crystal inputs and provides differential clock outputs. It operates within a supply voltage range of 3.135V to 3.465V and functions at temperatures between 0°C and 70°C. Packaged in a 56-TSSOP surface-mount case, it serves as a dedicated timing solution for high-performance computing systems requiring precise clock distribution.

Procurement Notes

Verify the 56-TSSOP package dimension (0.240 inch width) and the specific operating temperature range of 0°C to 70°C against design requirements. Confirm that the 3.135V to 3.465V supply voltage aligns with the target system power rails. Ensure the crystal input interface matches the source oscillator specifications before integration.

Selection Notes

Select this component when an AMD-compatible clock architecture with a 1:16 division ratio is required. It is suitable for designs needing differential outputs up to 280MHz. Consider the commercial temperature range (0°C to 70°C) and ensure the 56-pin TSSOP footprint fits the PCB layout constraints. Verify compatibility with the specific AMD chipset generation supported by this part number.

Part Context

This device belongs to Renesas' application-specific clock and timing portfolio. It is categorized under system clock chips intended for embedded or specialized computing environments. The part replaces older discrete clocking solutions by integrating multiple outputs and PLL functionality into a single 56-pin package.

Replacement Considerations

Check for direct pin-to-pin replacements within the same K8 series family. Verify if newer generations support the same 1:16 ratio and 280MHz limit while offering extended temperature ranges or updated packaging options.
