Procurement Notes

Verify the specific suffix requirements against your design schematic, as ordering codes may vary based on packaging preferences such as tape and reel or cut tape. Confirm that the 80 Ohm ESR and 8pF load capacitance align with your oscillator circuit design to ensure proper startup and frequency accuracy. Check current availability status directly with authorized distributors, as lead times can fluctuate based on production schedules and regional demand.

Selection Notes

Select this component when a standard 14.31818 MHz reference is required for general-purpose applications within the commercial temperature range. Ensure the 80 Ohm ESR is compatible with the driving circuit's capability, as higher ESR values may impact oscillation reliability in some designs. Compare against the NX3225GA series datasheet for detailed electrical characteristics and mechanical dimensions to verify fitment within the target PCB layout constraints.
