Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable and within the specified operating range to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues.
Selection Notes
Select this component when a low-profile, low-voltage oscillator with power-down capability is required. The LVCMOS output ensures compatibility with standard CMOS logic families. Consider the thermal characteristics and operating temperature range if the application involves extreme environmental conditions or high-density board layouts.
