• Includes power-down functionality to reduce consumption during standby
• Utilizes a compact 4-SMD no lead surface mount package

Applications

• Battery-powered portable devices
• General purpose clock signal generation
• Digital circuit timing references

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Check for any recent revisions to the datasheet regarding thermal or mechanical constraints.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small footprint. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Ensure the operating temperature range meets the environmental requirements of the final application.

Part Context

This part belongs to the QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages within a standardized 2.0x1.6 mm package. The '18' prefix indicates the 1.8V supply variant, distinguishing it from other voltage options in the family.

Replacement Considerations

Direct substitutes include other 10.05 MHz LVCMOS oscillators in a 2.0x1.6 mm SMD package with 1.8V operation. Verify pin compatibility and output drive strength when considering alternatives from different manufacturers.
