18QHTF21-28.300-OE

Oscillators Overview

The 18QHTF21-28.300-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 28.3 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Supports active enable and disable control states
• Utilizes quartz-based timing stability mechanisms

Oscillators Applications

• General clock generation for embedded systems
