18QHTF21-28.636363-OE

Oscillators Overview

The 18QHTF21-28.636363-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 28.636363 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interfacing
• Features enable/disable control for power optimization
• Utilizes a leadless SMD package for space-constrained designs

Oscillators Applications

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

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 28.636363 MHz clock source is required with low-voltage operation. Consider the enable pin feature if dynamic power saving is necessary. Evaluate the thermal performance and operating temperature range to ensure reliability under your specific environmental conditions compared to alternative oscillator families.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a single package type. This specific model provides a non-standard frequency option, distinguishing it from common integer multiples like 25MHz or 50MHz found in general inventory.

Oscillators Replacement Considerations

Direct substitutes must match the 28.636363 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and electrical characteristics with other manufacturers' offerings if Mercury Electronics parts are unavailable.
