18QHTF21-14.700-PD

Oscillators Overview

The 18QHTF21-14.700-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.7 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode to reduce consumption when inactive. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component serves as a precise clock source for digital circuits requiring stable timing signals.

Oscillators Feature Summary

• Integrates LVCMOS output interface for direct compatibility with standard digital logic families.
• Supports active and standby modes via power-down control to optimize energy efficiency.
• Utilizes a lead-free surface-mount package design suitable for automated assembly processes.

Oscillators Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces
• Synchronization sources for digital signal processing systems

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure joint integrity.

Oscillators Selection Notes

Select this component when a 14.7 MHz clock signal is required with low voltage operation. Consider the LVCMOS output swing if interfacing with 3.3V or 5V logic without level shifting. Evaluate the need for power-down functionality if battery life or thermal management is critical. Compare package size constraints against available board space.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The '-PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from standard continuous-operation variants in the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 14.7 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute parts support the power-down feature if required. Cross-reference electrical specifications such as phase noise and jitter to ensure system performance is maintained.
