Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.
Selection Notes
Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The enable/disable feature makes it suitable for battery-powered or power-sensitive applications. Consider the 4-SMD package size for high-density board layouts. Verify that the 13.533 MHz frequency meets the specific timing needs of the target digital interface or processor.
