18QHTF21-40.0096-PD

Oscillators Overview

The 18QHTF21-40.0096-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 40.0096 MHz and utilizes LVCMOS output logic levels. The device is designed for operation with a 1.8V supply voltage and includes a standby or power-down function to reduce consumption when inactive. It is housed in a compact 4-SMD, no lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power management
• Provides LVCMOS signal output compatibility

Oscillators Applications

• Embedded system clock generation
• Digital signal processing timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply rail can maintain stable voltage under all operating conditions to ensure oscillator reliability. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions and thermal requirements specified in the official datasheet.

Oscillators Selection Notes

Select this component when a precise 40.0096 MHz reference is required in space-constrained designs. The choice depends on the necessity for low-power standby functionality and compatibility with 1.8V logic families. Evaluate the environmental stability needs against the standard specifications provided by the manufacturer.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors and low voltage operation, targeting portable electronics and compact digital devices requiring reliable timing sources.

Oscillators Replacement Considerations

Direct substitutes must match the 40.0096 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before cross-referencing with other manufacturers' offerings.
