18QHTF21-3.684-OE

Oscillators Overview

The 18QHTF21-3.684-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fundamental frequency of 3.684 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and features an Enable/Disable function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Oscillators Feature Summary

• Supports active enable and disable control functions
• Delivers LVCMOS signal output compatibility
• Operates on a single 1.8V power supply rail

Oscillators Applications

• Embedded system clock generation
• Microcontroller timing sources
• Digital communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout orientation and lead-free compliance status. Ensure the selected variant matches the required operating temperature range and stability specifications for the target application environment before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and precise enable/disable control is required for power optimization. The 3.684 MHz frequency is suitable for baud rate generation or basic clocking needs where moderate stability suffices. Consider the small form factor for space-constrained PCB layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized footprint. The OE suffix generally denotes specific packaging or testing configurations defined by the manufacturer for distribution channels.

Oscillators Replacement Considerations

Direct substitutes must match the 3.684 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and electrical characteristics with alternative manufacturers' equivalent XO components before implementation.
