Oscillators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the 6-VDFN footprint matches the target PCB design constraints. Ensure the 2.25V to 3.6V supply voltage aligns with the system power rails. Check for RoHS compliance status if required by project specifications. Validate the 10 ppm stability requirement against the application's timing tolerance needs.

Oscillators Selection Notes

Select this component when a small form factor is critical due to its 3.2 x 2.5 mm dimensions. Choose the CMOS output variant for direct compatibility with standard digital logic families. Consider the 10 ppm stability for applications demanding higher precision than standard 50 ppm oscillators provide. Evaluate the -40°C to +85C range against environmental conditions to ensure reliable operation.
