18QHTF21-23.400-OE

Oscillators Overview

The 18QHTF21-23.400-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fundamental frequency of 23.4 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications. The component supports a maximum supply current of 24mA and offers frequency stability of ±50ppm across its operating temperature range.

Oscillators Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Includes hardware enable/disable pin for active power state control
• Utilizes quartz crystal base resonator for precise timing generation

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's latest datasheet to confirm exact electrical tolerances and pinout configurations. Ensure the 1.8V supply rail matches the target circuit design before integration. Cross-reference the 4-SMD package dimensions with PCB footprint libraries to guarantee mechanical fit during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs requiring dynamic clock gating. Consider the ±50ppm stability requirement against system jitter budgets before finalizing the part choice.
