Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to prevent assembly issues. Cross-reference the datasheet for operating temperature range compliance.

Oscillators Selection Notes

Select this component when a 41.44 MHz clock source is required with low-voltage operation. Consider the LVCMOS output swing compatibility with downstream logic families. Evaluate the need for enable/disable control versus always-on operation. Assess the thermal performance within the specified operating temperature range for the intended environment.
