18QHTF21-22.080-OE

Oscillators Overview

The 18QHTF21-22.080-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22.08 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an integrated enable/disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

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

Oscillators Applications

• Embedded systems requiring precise timing references
• Consumer electronics with limited board space
• Industrial control modules needing stable clock signals

Oscillators Procurement Notes

Verify the specific suffix 'OE' corresponds to the enable/disable feature when sourcing replacements. Confirm that the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD footprint aligns with the PCB layout specifications. Check for RoHS compliance status if required by project regulations. Validate the manufacturer part number against official Mercury Electronics documentation to avoid counterfeit components.

Oscillators Selection Notes

Select this component when a 22.08 MHz clock signal is required with low voltage operation. The enable pin makes it suitable for battery-powered devices where power conservation is critical. The small 2.0x1.6mm package is ideal for high-density PCB layouts. Consider the LVCMOS output compatibility with the receiving digital logic family. Evaluate thermal requirements based on the operating environment.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile surface-mount timing solutions.
