18QHTF21-13.560064-OE

Overview

The 18QHTF21-13.560064-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.560064 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm. This component serves as a precise clock source for electronic circuits requiring stable frequency generation.

Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact surface-mount design suitable for space-constrained applications

Applications

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

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues during operation.

Selection Notes

Select this component when a 13.56 MHz frequency is required with low-voltage operation. Consider the 2.0x1.6mm footprint for PCB layout constraints. Evaluate the need for enable/disable control if power efficiency is a priority. Compare performance metrics such as phase noise and stability against alternative oscillators from the same manufacturer series.

Part Context

This part belongs to the QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. The 'OE' suffix typically indicates a specific ordering or packaging variant defined by the manufacturer. These components are designed for reliability in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 13.56 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation from Mercury Electronics, such as the 25QHTF21-13.560064-OE which shares the same frequency but operates at 2.5V. Verify pinout and electrical characteristics before substitution.
