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 power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions. Check if the power-down control signal is integrated into the design to utilize the standby feature effectively.

Oscillators Selection Notes

Select this component when a precise 37.056 MHz reference is required for LVCMOS-compatible digital circuits. The choice is appropriate for space-constrained designs due to the small 2.0x1.6mm form factor. Consider the power-down capability if energy efficiency during idle states is a priority. Ensure the operating temperature range meets the environmental conditions of the final application.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer has decades of experience in quartz crystal production. The 18QHTF21 series typically offers reliable performance for general-purpose timing applications. The PD suffix indicates the inclusion of a power-down pin or function within the package.

Oscillators Replacement Considerations

Direct substitutes must match the 37.056 MHz frequency, LVCMOS output, and 1.8V supply voltage. Compatible packages include 4-SMD No Lead types with identical 2.0x1.6mm dimensions. Verify that alternative components support the same operating temperature range and power-down functionality to ensure seamless integration without redesign.
