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's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper solder joint integrity and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator with enable control is required. The LVCMOS output suits standard digital interfaces. Consider the 1.8V operating voltage constraint. The 4-SMD package offers space efficiency for dense board layouts compared to larger through-hole alternatives.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer specializes in quartz-based frequency control products. The model number indicates a specific frequency variant within their SMD oscillator lineup, distinguished by its enable pin capability and small form factor suitable for modern electronics.

Oscillators Replacement Considerations

Substitute only with identical Mercury Electronics 18QHTF21 series parts sharing the exact 36.1893 MHz frequency. Verify that any alternative maintains the same LVCMOS output type, 1.8V supply requirement, and 4-SMD package dimensions to ensure electrical and mechanical compatibility.
