18QHTF21-13.584-OE

Overview

The 18QHTF21-13.584-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.584 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.

Feature Summary

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

Applications

• Timing signal generation in electronic devices
• Clock source for digital circuits
• Embedded systems requiring stable frequency reference

Procurement Notes

Verify the exact frequency specification of 13.584 MHz against system requirements. Confirm the 1.8V supply voltage compatibility with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for RoHS compliance status if required by project specifications. Validate the LVCMOS output level with connected logic inputs.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. Consider the enable/disable functionality for power-sensitive designs. The small form factor suits space-constrained layouts. Verify that LVCMOS output levels are compatible with downstream digital components. Ensure the operating temperature range meets environmental conditions.
