Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout silkscreen and copper pad dimensions to guarantee proper solder joint integrity during reflow processes.

Oscillators Selection Notes

Select this component when a precise 47.3337 MHz clock source is required with low voltage operation. Consider the LVCMOS output swing levels relative to the receiving input thresholds. Evaluate the thermal performance and operating temperature range specifications to ensure reliability under the expected environmental conditions of the final assembly.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies within the same physical footprint. The suffix OE indicates specific packaging or handling characteristics defined by the manufacturer. This family targets cost-sensitive applications requiring stable frequency generation in small form factors.

Oscillators Replacement Considerations

Direct replacements must match the 47.3337 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as jitter and phase noise if critical. Cross-reference with other Mercury Electronics models in the H21 or similar series for potential equivalents.
