Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge sensitivity during installation.

Oscillators Selection Notes

Select this component when a precise 29.7 MHz timing source is required for low-power applications. The choice is driven by the need for LVCMOS compatibility and a small form factor. Consider the power-down capability if battery life or thermal management is a priority. Validate that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, which specializes in quartz crystal products. The manufacturer has a history of producing frequency control components since 1973.
