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 voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper solder joint formation and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V clock source is required for space-constrained designs. The enable/disable feature makes it suitable for battery-operated devices where power conservation is critical. Verify that the LVCMOS output swing meets the input threshold requirements of the receiving logic gates within the application circuit.
