Procurement Notes

Verify the specific suffix '057' against official Renesas documentation to confirm the exact frequency configuration and pinout compatibility. Ensure the ordering part number matches the required output format (LVDS/LVPECL) as defined in the datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to align with assembly process requirements.

Selection Notes

Select this component when a single PLL with four differential outputs is required for system synchronization. Consider the 32-VFQFN package for space-constrained designs. Evaluate thermal performance within the specified operating temperature range. Verify that the input crystal frequency supports the desired output generation capabilities defined in the programming guide.
