Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Oscillators Selection Notes

Select this component when a precise 30.714747 MHz timing source is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage constraint and ensure the application can support the specified supply range. The small form factor makes it appropriate for dense board layouts where larger packages are not feasible. Evaluate the need for power-down functionality if battery life or thermal management is a priority.
