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 package dimensions fit within your PCB footprint 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 LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD no-lead form factor for space-constrained layouts. Verify that the 3.1457 MHz frequency meets the exact timing needs of the target application compared to standard frequencies like 3.6864 MHz.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which offers various frequency options within the same package and electrical specification framework. The series is characterized by its small footprint and low voltage operation, catering to modern portable and compact electronic devices.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with different frequencies but identical pinouts and electrical characteristics, such as the 18QHTF21-3.1815-OE, provided the frequency difference is acceptable for the application.
