18QHTF21-10.492-OE

Overview

The 18QHTF21-10.492-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.492 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports active enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a standard crystal oscillator for precise timing applications

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix to ensure correct output logic and enable pin configuration. Confirm that the 1.8V supply voltage matches the target circuit design requirements. Check the package outline drawing for mechanical fit within the PCB layout constraints. Ensure the operating temperature range aligns with the intended environmental conditions.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. Consider the 2.0x1.6mm footprint for space-constrained designs. Evaluate the need for an enable pin if power cycling or clock gating is necessary. Compare against other frequencies in the 18QHTF21 series for different timing needs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which offers various frequencies in a small SMD package. The series typically includes options with different output voltages and control features. It is part of Taiwan's quartz crystal manufacturing industry history dating back to 1973.

Replacement Considerations

Check for parts with identical 10.492 MHz frequency, 1.8V operation, and LVCMOS output. Verify compatible package dimensions and pinout configurations for direct replacement.
