18QHTF21-106.920-PD

Overview

The 18QHTF21-106.920-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 106.92 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range suitable for general electronic applications.

Feature Summary

• Supports low-voltage operation at 1.8V for efficient power consumption
• Includes a power-down standby mode to reduce current draw when inactive
• Provides stable LVCMOS output signals for digital circuit interfacing
• Utilizes a small surface-mount package design for space-constrained layouts

Applications

• Battery-powered portable electronic devices requiring low current
• Digital communication systems utilizing LVCMOS interfaces
• Embedded systems needing precise timing references
• General-purpose clock generation for microcontrollers

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 handling instructions related to electrostatic discharge during assembly.

Selection Notes

Choose this oscillator when a 106.92 MHz clock signal is required with minimal power usage. The 1.8V specification makes it suitable for modern low-voltage digital logic families. Consider the power-down feature if the system has idle periods where clocking can be suspended. The small form factor aids in high-density board designs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-power crystal oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. These components are designed for applications demanding reliable timing with strict size and power constraints.

Replacement Considerations

Direct substitutes must match the 106.92 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and stability before swapping manufacturers.
