18QHTF21-2.1809-OE

Oscillators Overview

The 18QHTF21-2.1809-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fundamental frequency of 2.1809 MHz and utilizes LVCMOS output logic. The device supports a 1.8V supply voltage 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 logic interface
• 1.8V operating supply voltage
• Enable/Disable control functionality
• 4-SMD No Lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Low power electronic circuits

Oscillators 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 4-SMD No Lead footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-frequency, low-voltage timing source is required. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the enable pin if power conservation is critical. Verify compatibility with the target application's temperature range and electromagnetic interference constraints prior to integration.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products since 1973. The company produces quartz crystals, oscillators, and filters. This part belongs to their line of standard XO devices, characterized by stable frequency generation and compact packaging solutions for modern electronics.

Oscillators Replacement Considerations

Compatible substitutes include other 2.1809 MHz LVCMOS oscillators from Mercury Electronics such as the 18QHTF21-2.1809 variant without the OE suffix, provided the enable feature is not strictly required. Cross-reference with other manufacturers offering identical frequency, voltage, and package dimensions.
