Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 14.18757 MHz clock source is required for low-power applications. The choice depends on the necessity for an LVCMOS interface and the availability of a 1.8V power rail. Consider the physical size constraints due to the small 2.0x1.6mm package. Evaluate the need for power-down functionality to manage energy consumption effectively in battery-operated devices.
