Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's clock input specifications. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet to guarantee proper solder joint formation and mechanical stability during reflow processes.

Selection Notes

Select this component when a precise 100.005 MHz reference is required for LVCMOS-compatible digital circuits. The choice depends on the necessity for low-voltage operation at 1.8V and the availability of an enable pin for power management. Consider the thermal characteristics and operating temperature range relative to the intended environment. Evaluate the size constraints of the enclosure to ensure the small form factor fits within the designated area.
