• Telecommunications infrastructure timing

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm RoHS compliance status via official documentation. Ensure storage conditions account for moisture sensitivity levels prior to surface mount assembly. Validate package marking against datasheet specifications to prevent counterfeit substitution.

Selection Notes

Select this component when designing systems requiring precise clock distribution with flexible frequency division. Consider the 56-VFQFN package constraints for PCB layout and thermal dissipation requirements. Evaluate the 1.035 GHz operational limit against target signal frequencies to ensure adequate performance margins for high-speed interface applications.

Part Context

This part belongs to the miSmartBuffer series, designed for versatile clock management in complex electronic systems. It serves as a critical timing element in multi-standard platforms where jitter reduction and flexible output scaling are essential for maintaining signal integrity across various high-speed interfaces.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Cross-reference pin compatibility and electrical specifications before implementation. No direct substitutes are confirmed in public sources without explicit manufacturer validation.
