18QHTF21-32.50794-OE

Oscillators Overview

The 18QHTF21-32.50794-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 32.50794 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable pin for power control
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• Digital signal processing timing references
• Communication equipment clock sources
• Embedded system microcontroller clocks

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a stable 32.50794 MHz reference is required for LVCMOS-compatible digital circuits. The choice is driven by the need for low-voltage operation at 1.8V and the integration of enable functionality. Consider the small form factor of the 4-SMD package for space-constrained board layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's quartz industry. This series typically offers standard oscillators with various frequencies and voltage levels, serving as core timing components for electronic systems.

Oscillators Replacement Considerations

Direct substitutes must match the 32.50794 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent enable/disable functionality and electrical characteristics from other manufacturers if cross-referencing.
