Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable and within the specified operating range. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to avoid assembly issues. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure component integrity during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The choice is driven by the need for a small form factor suitable for space-constrained designs. Consider the availability of the specific 38.707 MHz frequency variant. Evaluate the power-down feature if battery life or thermal management is a critical design constraint for the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products.
