Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V enable pin logic levels match your microcontroller or FPGA I/O standards. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly errors.

Oscillators Selection Notes

Select this component when a low-power, small-footprint oscillator with enable control is required for 3.59 MHz applications. Consider the LVCMOS output swing limits relative to your downstream logic family. Evaluate the thermal performance and soldering profile compatibility for the no-lead package during the manufacturing process planning phase.
