18QHTF21-14.4756-PD

Oscillators Overview

The 18QHTF21-14.4756-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 14.4756 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby or power-down functionality to manage power consumption
• Utilizes a leadless 4-SMD surface-mount package design

Oscillators Applications

• General-purpose digital timing circuits
• Embedded systems requiring stable clock references
• Consumer electronics with low-voltage operation requirements

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 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 14.4756 MHz reference is needed with low-power capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V operating voltage as a primary constraint for power supply design. The leadless package offers space-saving benefits for dense board layouts compared to traditional through-hole options.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has a long history in Taiwan's crystal industry. This specific model represents a standard XO variant within their portfolio, distinguished by its unique frequency and low-voltage operation characteristics.

Oscillators Replacement Considerations

Direct substitutes must match the 14.4756 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before swapping. Generic oscillators may not meet the specific standby current or phase noise specifications implied by this model.
