Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the specified operating range. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to prevent assembly errors. Check for any specific handling instructions regarding electrostatic discharge protection during storage and installation.

Oscillators Selection Notes

Select this component when a precise 13.91222 MHz timing source is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and the need for a power-down feature for energy management. Evaluate the small 2.0x1.6mm form factor against available board space. Compare performance characteristics such as phase noise and stability if critical timing accuracy is necessary for the application.
