Procurement Notes

Verify the specific suffix '024' against official Renesas documentation to confirm the exact frequency plan and pinout configuration. Ensure compatibility with the required operating temperature range and voltage levels. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the part number with the latest datasheet revision to avoid obsolete variants.

Selection Notes

Select this component when ultra-low phase noise and jitter attenuation are primary requirements. Compare against the broader 8T49N240 family to ensure the specific output count and package type meet board space constraints. Verify that the supported input frequencies align with available reference clocks. Consider thermal management requirements given the dense VFQFPN-40 packaging.

Part Context

This part belongs to the Renesas FemtoClock NG series, designed for advanced jitter cleaning and frequency synthesis. The 8T49N240 variant specifically targets applications requiring high precision and low phase noise. It integrates programmable logic to generate multiple clock signals from a single reference source, enhancing system reliability and reducing electromagnetic interference.

Replacement Considerations

Consult official substitution lists for direct replacements such as other 8T49N240 suffixes or updated revisions. Verify electrical parameter equivalence before swapping. Generic family members may differ in output drive strength or package dimensions.
