Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors. Check for any specific reflow soldering profile recommendations provided by the manufacturer to maintain component integrity during manufacturing.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for direct interfacing with standard digital logic inputs. Consider the small form factor if space constraints are critical on the PCB layout. Verify that the enable/disable feature meets power efficiency goals for battery-operated devices. Compare performance metrics such as jitter and stability against other available oscillators in the same series.
