Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications 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 any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable/disable feature for power efficiency. The LVCMOS output is appropriate for standard digital logic interfaces. Consider the small form factor of the 4-SMD package if space constraints are critical. Verify that the 18.944 MHz frequency meets the exact timing needs of the target application.
