Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any specific handling instructions related to the no-lead package during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the physical dimensions of the 4-SMD package for space-constrained designs. Validate that the 36.864 MHz frequency meets the system clock requirements without additional dividers.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard crystal oscillators. The manufacturer specializes in frequency control products including quartz crystals and filters. The 18QHTF21 series typically offers various frequencies within a small form factor, catering to consumer electronics and industrial applications requiring reliable timing sources.

Oscillators Replacement Considerations

Direct substitutes include other 36.864 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Fox Electronics or Epson.
