Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 65.0158 MHz timing source is required within a low-power 1.8V environment. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the thermal performance and operating temperature range to ensure reliability under the intended environmental conditions.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation. This model provides a stable clock source for applications needing a specific high-frequency reference in a small form factor.

Replacement Considerations

Direct substitutes must match the 65.0158 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Cross-reference with other manufacturers offering similar XO specifications to ensure functional equivalence without redesigning the host circuit.
