18QHTF21-14.617188-PD

Oscillators Overview

The 18QHTF21-14.617188-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.617188 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function to reduce power consumption when inactive. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes standby mode capability for power management
• Utilizes a leadless surface-mount package design

Oscillators Applications

• General clock signal generation for digital circuits
• Timing reference for low-voltage embedded systems
• Portable electronic devices requiring small form factors

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a precise 14.617188 MHz timing source is required for 1.8V logic interfaces. Consider the standby feature if power efficiency is critical during idle periods. Evaluate the physical size constraints of the application to ensure the 2.0x1.6mm package fits within the available board space compared to larger oscillator options.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series typically offers various frequencies within a standardized small outline package format. These oscillators are designed to replace discrete crystal and resonator combinations with integrated solutions for simplified PCB layout.

Oscillators Replacement Considerations

Direct replacements must match the 14.617188 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar small-footprint XO components if availability is an issue.
