18QHTF21-13.5755-OE

Overview

The 18QHTF21-13.5755-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5755 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component is designed to operate within a temperature range of -40°C to 85°C.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power control
• Utilizes a compact 4-SMD no lead surface mount package

Applications

• General purpose timing circuits
• Embedded systems requiring low voltage operation
• Consumer electronics with space constraints

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0 x 1.6 mm 4-SMD no lead package dimensions to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 13.5755 MHz clock signal is required in a low-profile surface mount format. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the operating temperature range of -40°C to 85°C to ensure reliability in varying environmental conditions compared to commercial grade alternatives.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix likely denotes specific packaging or operational characteristics defined by the manufacturer. This model represents a standard XO variant optimized for cost-effective mass production in consumer devices.

Replacement Considerations

Direct substitutes must match the 13.5755 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and thermal specifications. Cross-reference with other manufacturers offering similar small-form-factor oscillators if Mercury Electronics parts are unavailable.
