Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity and pin alignment against SC-70-6 specifications. Check for moisture sensitivity handling requirements despite MSL rating 1. Ensure supply chain sources provide traceability documentation. Validate that the specific revision matches design requirements before final procurement decisions.

Selection Notes

Select this component when a fixed divide-by-8 ratio is required within the 1.5GHz operational limit. Consider the SC-70-6 package constraints for PCB layout and thermal management. Evaluate UltraCMOS® technology benefits for low-power applications. Assess compatibility with existing CMOS logic levels in the system architecture. Verify that the discontinued status does not impact long-term production viability.
