18QHTF21-14.680064-PD

Oscillators Overview

The 18QHTF21-14.680064-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.680064 MHz with an LVCMOS output signal. The device functions at a supply voltage of 1.8V and includes a power-down feature for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0x3.2 mm. The component is RoHS compliant.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down functionality for energy management
• Provides standard LVCMOS output signals

Oscillators Applications

• General purpose digital clock generation
• Embedded system timing references
• Consumer electronics circuitry

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the power-down capability against the manufacturer's official datasheet. Ensure the 5.0x3.2 mm footprint matches the target PCB layout. Confirm RoHS compliance status if required by environmental regulations. Cross-reference the part number with the distributor's current documentation to ensure accuracy.

Oscillators Selection Notes

Select this component when a precise 14.680064 MHz reference is required in space-constrained designs. The 1.8V supply requirement dictates compatibility with low-voltage logic families. The power-down feature is essential for battery-operated applications requiring extended standby life. Verify that the LVCMOS output swing meets the input requirements of the receiving circuit.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and package sizes. The 18QHTF21 variant specifically denotes the 1.8V supply and 5.0x3.2 mm form factor. This series is designed for high-reliability applications in portable and industrial electronics.

Oscillators Replacement Considerations

The 18QHTF21-14.680064-OE is a related variant offering enable/disable control instead of power-down. Direct substitution requires verifying if the enable/disable interface is compatible with the existing design logic. Other frequencies in the 18QHTF21 series share the same package but differ electrically.
