18QHTF21-3.786-OE

Oscillators Overview

The 18QHTF21-3.786-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 3.786 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management in system designs. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated enable/disable functionality for power control
• Operates on a 1.8V supply voltage rail
• Utilizes a 4-SMD no-lead surface mount package

Oscillators Applications

• General clock signal generation for embedded systems
• Timing reference for low-power digital circuits
• Synchronization sources in consumer electronics

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability data to ensure compliance with your project standards.

Oscillators Selection Notes

Select this component when a precise 3.786 MHz timing source is required for LVCMOS-compatible digital logic. The choice is driven by the need for low-voltage operation at 1.8V and the requirement for remote enable/disable control to manage system power states. Consider the small form factor of the 4-SMD package if space constraints are critical in the application design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the XO category. Mercury Electronic is a established supplier of frequency control products, including quartz crystals and oscillators, with manufacturing history dating back several decades in Taiwan.

Oscillators Replacement Considerations

Direct substitutes must match the 3.786 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify equivalent enable/disable functionality. Consult official cross-reference lists or distributor databases for confirmed compatible parts from other manufacturers.
