Oscillators Procurement Notes

Verify the specific frequency tolerance and temperature range requirements against system specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no lead package dimensions are compatible with the PCB footprint. Check for any specific handling requirements related to the surface mount technology used in this component.

Oscillators Selection Notes

Select this component when a 25.55 MHz timing source is required with low power consumption constraints. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the ±50ppm stability for applications where moderate precision is sufficient. The wide operating temperature range allows for use in industrial or automotive environments requiring reliability under thermal stress.

Oscillators Part Context

This model belongs to the 18QHTF series of oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The '18' prefix often indicates the 1.8V supply variant. The 'OE' suffix may denote specific packaging or testing configurations. This part is distinct from other variants like the 3.3V versions or different package types within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 25.55 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility for the 4-SMD no lead package. Ensure equivalent stability and temperature ratings are maintained. Cross-reference with Mercury Electronics documentation for approved alternative part numbers.
