Application Specific Clock/Timing Procurement Notes

Verify the specific suffix '1HGLFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure the source document explicitly lists this part number as active or available, as similar CK505 derivatives may have varying lifecycle statuses. Cross-reference the 64-TSSOP package dimensions with the datasheet to ensure mechanical compatibility.

Application Specific Clock/Timing Selection Notes

Select this component when a CK505-compatible solution is required for Intel-based designs. Verify that the 0°C to 70°C operating temperature range meets the system's environmental requirements. Confirm that the single-ended crystal input and differential HCSL/LVPECL output signaling match the target chipset's clocking architecture. Check if the integrated voltage regulator simplifies the power design compared to external regulator solutions.

Application Specific Clock/Timing Part Context

This part belongs to the family of CK505 derivative clock generators used primarily in PC and server platforms. It serves as a direct replacement or alternative for standard Intel CK505 clock synthesizers, offering similar pinouts and functionality while potentially providing enhanced integration such as built-in voltage regulation and series termination resistors.
