18QHTF21-14.368-PD

Oscillators Overview

The 18QHTF21-14.368-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.368 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Compact surface-mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a standard 14.368 MHz frequency. The LVCMOS output is suitable for direct interfacing with CMOS-compatible logic families. Consider the power-down feature if battery life or thermal management is a critical constraint in the final application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small SMD form factor. The series typically provides standard XO options with LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 14.368 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility for the power-down function. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions to ensure functional interchangeability.
