18QHTF21-3.480-OE

Oscillators Overview

The 18QHTF21-3.480-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 3.48 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, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the enable/disable pin configuration matches the control logic of the host microcontroller or FPGA to ensure proper operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered or power-sensitive applications. Consider the small 4-SMD footprint for space-constrained PCB layouts. Verify that the 3.48 MHz frequency meets the specific timing needs of the application.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF21 series of standard crystal oscillators. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific ordering or packaging variations defined by the manufacturer. This series is part of Mercury's broader portfolio of quartz-based frequency control products established since 1973.

Oscillators Replacement Considerations

Direct replacements must match the 3.48 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check pinout compatibility and enable/disable logic polarity. Cross-reference with other Mercury 18QHTF21 variants or industry-standard equivalents if available.
