Oscillators Procurement Notes

Verify the specific suffix '-R' indicates tape-and-reel packaging when sourcing components. Confirm that the 1.8V supply requirement aligns with target circuit logic levels. Ensure the ±25ppm stability meets system timing requirements. Check RoHS compliance status if required by project specifications. Validate the 4-SMD footprint against PCB layout constraints.

Oscillators Selection Notes

Select this model for applications requiring precise 12.288 MHz timing with low voltage operation. Consider the ±25ppm stability for general-purpose digital interfaces. Evaluate the -20°C to +70°C range against environmental conditions. Compare against TCXO options if tighter stability is needed. Ensure the HCMOS output drives compatible loads without excessive current draw.
