Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly and long-term performance stability.

Oscillators Selection Notes

Select this model when a 2.048 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage as a primary constraint for power supply design. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Evaluate the need for power-down capability if battery life or thermal management is critical. Compare against other frequencies in the 18QHTF21 series if different clock speeds are needed.
