The device supports a supply voltage of 1.8V and includes a standby (power down) function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Integrated standby power down capability
• Compact 4-SMD no lead surface mount package

Applications

• General purpose clock generation
• Digital signal processing systems
• Embedded controller timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the part number suffix to confirm the exact package variant and pin configuration provided by the manufacturer.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down feature makes it suitable for battery-powered or energy-efficient designs. Consider the small form factor of the 4-SMD package for space-constrained layouts. Verify compatibility with the target digital logic levels and ensure the operating temperature range meets environmental specifications.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package. The series provides standardized LVCMOS outputs and low-voltage operation. Other variants in this family include different frequencies such as 51.2 MHz or 6.000 MHz, sharing similar electrical characteristics and physical dimensions.

Replacement Considerations

Direct substitutes may include other 18QHTF21 series parts with identical frequency if available. Generic replacements require matching LVCMOS output, 1.8V supply, and 4-SMD package. Verify frequency accuracy and phase noise specifications against the original datasheet to ensure functional equivalence.
