Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and date codes upon receipt. Ensure compatibility with existing design specifications before integration. Check for alternative sourcing options if new production units are required. Validate electrical parameters against original datasheet requirements during incoming inspection.

Selection Notes

Evaluate thermal management requirements given the -40°C to +85°C operating range. Consider power budget constraints relative to the sub-90 mA current draw. Assess frequency stability needs against the 2 ppb resolution capability. Verify interface compatibility with host system control logic. Review lifecycle status implications for long-term supply chain planning.
