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 no-lead footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Consult the official datasheet for detailed electrical characteristics and recommended soldering profiles to ensure reliable assembly.

Selection Notes

Select this component when a precise 11.067 MHz clock signal is needed for LVCMOS-compatible devices. The 1.8V operation makes it suitable for modern low-power portable electronics. The enable/disable feature allows for dynamic power management strategies. Consider the small 2.0x1.6 mm package size if board real estate is limited. Ensure the application environment does not exceed the specified operating temperature range defined in the manufacturer's documentation.
