Oscillators Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to ensure accuracy regarding the enable/disable feature and voltage requirements. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint design. Cross-reference the part number with the latest datasheet to validate the 25.650 MHz frequency specification before procurement.

Oscillators Selection Notes

Select this component when a 1.8V supply voltage is required for the clock source. Ensure the application supports LVCMOS logic levels for signal integrity. The enable/disable pin allows for system-level power optimization. Verify that the 4-SMD no-lead package fits within the available board space constraints.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, which focuses on small-form-factor timing solutions. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes specific operational characteristics or packaging variants defined by the manufacturer. This model represents a standard XO configuration rather than a temperature-compensated variant.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages with identical 25.650 MHz frequency. Check for compatible enable/disable pin configurations. Verify that alternative manufacturers offer similar jitter specifications and load capacitance requirements to ensure seamless integration without circuit redesign.
