18QHTF21-13.526-OE

Oscillators Overview

The 18QHTF21-13.526-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.526 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage range that includes 1.8V operation and features an enable/disable control function 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 interface for digital logic compatibility
• Integrated enable/disable pin for active power control
• Compact 4-SMD no-lead surface mount footprint

Oscillators Applications

• General clock signal generation in electronic devices
• Timing reference for low-voltage digital circuits
• Embedded systems requiring precise frequency stability

Oscillators Procurement Notes

Verify the specific operating voltage requirements against the target circuit design, as the datasheet indicates support for 1.8V but other voltages may be available in the series. Confirm the enable/disable functionality aligns with system power sequencing needs. Ensure the 4-SMD package dimensions fit the PCB layout constraints. Cross-reference the part number suffix to ensure the correct frequency tolerance and load capacitance specifications are met for the application.

Oscillators Selection Notes

Select this component when a stable 13.526 MHz reference is required for LVCMOS-compatible digital interfaces. The integrated enable feature makes it suitable for battery-powered or power-sensitive designs where dynamic power management is necessary. Consider the small form factor for space-constrained layouts. Evaluate thermal performance if the operating environment involves high ambient temperatures, although specific thermal data is not provided in the general overview.
