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 system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check the operating temperature range specifications to guarantee reliability under your intended environmental conditions.

Oscillators Selection Notes

Select this component when a 41.46 MHz clock source is required with low power consumption capabilities. The LVCMOS output is suitable for interfacing with standard digital logic families. Consider the physical size constraints of the 2.5x2.0mm package during board design. Evaluate the need for power-down features if battery life or thermal management is a priority in the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small form factor. The 'PD' suffix indicates the inclusion of a power-down pin or function. Similar parts in the series include different frequencies such as 51.2 MHz or 68.665 MHz, maintaining the same package and electrical characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 41.46 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility for the 4-SMD no-lead package. Parts like the 18QHTF21-41.460-OE may differ in packaging or specific electrical tolerances; confirm datasheet alignment before substitution.
