• Clock source for microcontroller and FPGA configurations

Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compatibility with required enable/disable pin configurations. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check the 4-SMD no-lead footprint dimensions against the PCB layout to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this model when a low-profile surface mount oscillator is required for 31.125 MHz applications. Ensure the design accommodates the 1.8V logic level and utilizes the enable feature if power management is necessary. Consider the thermal environment as the operating range extends to 85°C. Verify that the LVCMOS output swing meets the input requirements of the receiving device without additional buffering.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard XO oscillators. The series offers various frequencies and voltage options within a small SMD form factor. Similar models include variants with different frequencies such as 44.2 MHz or 31.330 MHz, maintaining the same package and electrical characteristics for interchangeable design purposes.

Oscillators Replacement Considerations

Direct substitutes must match the 31.125 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility for the enable function. Cross-reference with other manufacturers offering equivalent specifications in identical footprints to ensure seamless integration without PCB redesign.
