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 guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a stable 44.04 MHz clock source is required with low-voltage operation. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The enable pin allows for power management strategies by disabling the oscillator when not in use, reducing overall system power consumption.
