18QHTF21-18.0224-PD

Oscillators Overview

The 18QHTF21-18.0224-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 18.0224 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output logic

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. 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 18.0224 MHz reference is needed in space-constrained applications. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the power-down feature for battery-operated systems where standby current reduction is critical. Validate thermal performance within the specified operating temperature range.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, characterized by small form factors suitable for modern surface-mount assembly. The manufacturer has extensive experience in quartz frequency control products. This specific model represents a standard XO variant rather than a differential or spread-spectrum type.

Oscillators Replacement Considerations

Direct substitutes must match the 18.0224 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if available in official datasheets.
