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 PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V clock source is required for space-constrained designs. The LVCMOS output is suitable for standard logic families. Consider the power-down feature if energy efficiency during idle states is a priority. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The series offers various frequencies and packages. The 'PD' suffix indicates power-down functionality, while 'OE' would indicate enable/disable control. This model provides a stable timing solution for modern low-power electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 14.74772 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers offering identical pinouts and electrical characteristics to ensure seamless integration without redesign.
