18QHTF21-18.601-PD

Oscillators Overview

The 18QHTF21-18.601-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 18.601 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode to reduce power consumption
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low-power oscillators

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 footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data.

Oscillators Selection Notes

Select this component when a stable 18.601 MHz reference is required with low power consumption. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operating voltage if your system uses low-voltage power domains. The small form factor makes it appropriate for space-constrained designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates the power-down feature availability. Mercury Electronics is a established manufacturer of frequency control products based in Taiwan.

Oscillators Replacement Considerations

Direct substitutes must match the 18.601 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Check if alternative manufacturers offer equivalent performance metrics for timing stability and phase noise.
