18QHTF21-13.5815-OE

Overview

The 18QHTF21-13.5815-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.5815 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

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

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 13.5815 MHz frequency. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6mm footprint if board space is limited. The enable feature allows for dynamic power management in battery-operated devices.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a similar small form factor. The series typically features LVCMOS outputs and support voltages around 1.8V. The 'OE' suffix indicates the presence of an enable/disable control pin, distinguishing it from basic oscillators without this functionality.

Replacement Considerations

Direct substitutes must match the 13.5815 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative component supports the same enable/disable functionality and has compatible electrical characteristics such as phase noise and jitter specifications.
