18QHTF21-80.600-PD

Overview

The 18QHTF21-80.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 80.6 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down capability for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply rail stability meets the component's specifications to ensure reliable oscillation. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions accurately to maintain signal integrity.

Selection Notes

Select this component when a precise 80.6 MHz reference is required within a low-power design constraint. The choice depends on the necessity for LVCMOS compatibility and the availability of a 1.8V power domain. Consider the physical size constraints of the 2.0x1.6 mm package relative to the available board space.

Part Context

This part belongs to the Mercury Electronics XO series, designed for surface-mount applications. It represents a standard frequency option within the 18QHTF21 family, distinguished by its specific 80.6 MHz tuning and low-profile packaging suitable for dense electronic assemblies.

Replacement Considerations

Direct substitutes include other 80.6 MHz LVCMOS oscillators in similar SMD packages from different manufacturers, provided voltage and pinout compatibility are verified.
