• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Operates on a 1.8V single supply voltage

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage level. Ensure the 4-SMD no-lead footprint matches the target PCB layout. Cross-reference the part number with authorized distributors to avoid counterfeit components, as generic listings may not reflect the exact electrical specifications or package type defined in the manufacturer's datasheet.

Oscillators Selection Notes

Select this component when a 34.5504 MHz reference is required for 1.8V logic families. The LVCMOS output ensures direct interfacing with microcontrollers or FPGAs without additional level shifting. The enable pin allows for dynamic power control in battery-operated devices. Verify thermal stability requirements against the standard XO specifications provided in the official datasheet.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, which focuses on low-voltage, small-footprint timing solutions. The series typically offers various frequencies within a standardized package format. The 'OE' suffix indicates specific operational characteristics, such as the enable function, distinguishing it from standard variants in the same physical package family.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Users must consult official Mercury Electronics catalogs for cross-references or contact the manufacturer directly for compatible alternatives that match the 34.5504 MHz frequency, 1.8V voltage, and 4-SMD package constraints.
