• Embedded system clock generation

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's power rails. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 14.27643 MHz frequency specifically for audio or video sampling rate applications where this exact harmonic relationship is necessary.
