Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature offers power management flexibility compared to always-on oscillators. Consider the small form factor of the 4-SMD package for space-constrained designs. Validate that the 16.31725 MHz frequency meets the exact clocking needs of the target application without requiring external dividers or multipliers.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF series of quartz crystal oscillators. The manufacturer specializes in frequency control products including crystals, TCXOs, and VCTCXOs.
