18QHTF21-14.000-PD

Oscillators Overview

The 18QHTF21-14.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 14 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Provides stable clock signals using LVCMOS output logic
• Supports low voltage operation at 1.8V
• Includes standby mode for power reduction

Oscillators Applications

• Electronic systems requiring precise timing references
• Low voltage digital circuits
• Portable devices needing power-efficient clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit's power rails. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints to ensure proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a 14 MHz clock signal is required for low-voltage applications. The choice depends on the necessity for LVCMOS compatibility and the availability of a 1.8V power supply. Consider the physical size constraints due to the small 2.0x1.6 mm package. Evaluate if the standby feature is necessary for power management strategies in the final product design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing a common small form factor. The 'PD' suffix indicates the inclusion of a power-down function, distinguishing it from non-power-down variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 14 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as jitter and phase noise before substitution.
