18QHTF21-16.777215-OE

Oscillators Overview

The 18QHTF21-16.777215-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.777215 MHz and utilizes LVCMOS output logic levels. The device supports an active enable/disable control function and is powered by a 1.8V supply voltage. It is housed in a compact 4-SMD, No Lead surface-mount package designed for integration into space-constrained electronic circuits.

Oscillators Feature Summary

• Supports LVCMOS output signal compatibility
• Features integrated enable/disable control functionality
• Operates on a 1.8V power supply

Oscillators Applications

• General-purpose digital clock generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 16.777215 MHz reference is required for LVCMOS-compatible interfaces. The choice is driven by the need for low-voltage operation at 1.8V and the requirement for remote enable/disable capabilities. Consider the small form factor of the 4-SMD package for applications where board space is limited and surface-mount technology is preferred over through-hole alternatives.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, a manufacturer established in Taiwan specializing in quartz crystals since 1973. The series typically includes various frequencies such as 75.63 MHz and 50.256 MHz variants, all sharing similar package styles and operational characteristics like LVCMOS outputs and 1.8V supply requirements.

Oscillators Replacement Considerations

Direct substitutes within the same series include models such as 18QHTF21-16.764166-OE or 18QHTF21-50.256-OE, provided the frequency difference is acceptable for the application. Verify pinout and package dimensions remain identical when considering alternative frequencies from the same manufacturer.
