Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and electrical connection during assembly.

Oscillators Selection Notes

Select this component when a precise 19.982 MHz reference is required with low power consumption features. The LVCMOS output is compatible with standard digital logic families operating at 1.8V. Consider the physical size constraints of the 4-SMD package when designing the layout for high-density boards requiring minimal component profile.
