Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current documentation to ensure correct configuration. Confirm that the 1.8V supply voltage aligns with the target system requirements. Check the physical dimensions of the 4-SMD package against the PCB footprint. Ensure the LVCMOS output levels are compatible with the receiving logic inputs. Review the datasheet for any specific handling or soldering recommendations.

Oscillators Selection Notes

Select this component when a precise 3.6846 MHz clock source is required for low-power applications. The 1.8V operating voltage makes it suitable for modern portable devices. The enable/disable feature allows for power management strategies. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the LVCMOS output swing meets the noise margins of the connected components.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant. The HF likely denotes high-frequency performance within the series. The 32 may refer to the package code or series identifier. The OE suffix specifies the particular configuration or tape/reel packaging option provided by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators with identical 3.6846 MHz frequency and 4-SMD no lead package. Verify pinout compatibility and electrical specifications before substitution. Alternative parts must support the same enable/disable control function. Ensure thermal characteristics match the original design constraints.
