Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 35.318 MHz reference is required in space-constrained applications. The choice is driven by the need for low-voltage compatibility and power management features. Consider the physical size constraints due to the small SMD package. Evaluate the LVCMOS interface compatibility with downstream digital logic circuits to ensure signal integrity.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and voltage options. Similar models like the 18QHTF21-6.000-PD share the same package and voltage characteristics but differ in frequency. The series is known for providing reliable frequency control solutions in a miniature form factor suitable for modern portable electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 35.318 MHz frequency, 1.8V supply, and LVCMOS output. Models such as 18QHTF21-35.468-PD are similar but have different frequencies. Verify pinout and electrical parameters before substitution.
