18QHTF21-20.64384-OE

Oscillators Overview

The 18QHTF21-20.64384-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 20.64384 MHz and utilizes an LVCMOS output interface. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. 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 interface for digital logic compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm electrical characteristics and pinout configuration. Ensure that the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD package dimensions with PCB layout specifications to guarantee mechanical fit and soldering integrity during assembly processes.

Oscillators Selection Notes

Select this component when a stable 20.64384 MHz reference is required for LVCMOS-compatible digital systems. Consider the 1.8V operating voltage constraint and the need for active enable/disable control features. Evaluate the 4-SMD footprint against available board space and thermal dissipation requirements relative to other oscillator options in the same family.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a consistent small form factor. The 'OE' suffix often denotes specific ordering or packaging variations defined by the manufacturer, distinguishing it from base models without such identifiers.

Oscillators Replacement Considerations

Direct substitutes must match the 20.64384 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package. Verify pin-to-pin compatibility and electrical parameters with alternative manufacturers before implementation.
