18QHTF21-27.1727-OE

Oscillators Overview

The 18QHTF21-27.1727-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.1727 MHz and utilizes LVCMOS output logic. The device supports 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 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated Enable/Disable control functionality
• Compact 4-SMD No Lead surface-mount package

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD No Lead footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 27.1727 MHz clock source is required within low-power embedded designs. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small form factor for space-constrained applications where traditional through-hole or larger SMD oscillators cannot fit.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for high-reliability frequency control. The '18' prefix typically indicates the 1.8V operating voltage, while 'QHTF' denotes the specific package and performance class. The suffix '-OE' signifies the inclusion of an enable pin feature, allowing for power management control in the final system design.

Oscillators Replacement Considerations

Direct substitutes must match the 27.1727 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent electrical parameters such as phase noise and jitter if the application requires strict timing precision. Cross-reference with other manufacturers offering similar miniature oscillators with enable functions.
