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 enable pin logic levels are compatible with your controlling microcontroller or FPGA to guarantee proper operation of the oscillator's active and standby states.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside a specific 40.00833 MHz frequency. Consider the LVCMOS output type for direct interfacing with standard digital logic families. Evaluate the small form factor of the 4-SMD package against available PCB real estate constraints compared to larger leaded or alternative SMD oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF series of standard XO oscillators. The series typically offers various frequencies within a compact footprint. Mercury Electronic is a specialized manufacturer of frequency control products, including quartz crystals and oscillators, established in Taiwan since 1973, focusing on precision timing solutions for electronic industries.

Oscillators Replacement Considerations

Direct substitutes must match the 40.00833 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify equivalent electrical parameters such as phase noise and stability if critical. Cross-reference with other manufacturers offering similar ultra-small form factor oscillators with identical pinout and electrical specifications.
