18QHTF21-57.747-OE

Overview

The 18QHTF21-57.747-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 57.747 MHz and utilizes LVCMOS output logic. 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.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable functionality for power management
• Compact 4-SMD no lead surface mount package design

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low voltage operation

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 constraints. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent component damage during operation.

Selection Notes

Select this component when a stable 57.747 MHz clock source is required within a low-voltage 1.8V environment. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable pin feature if dynamic power saving or clock gating is necessary for the application. The small form factor suits space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The suffix OE indicates a specific configuration within the product line, distinguishing it from other variants in the same family.

Replacement Considerations

Direct substitutes must match the 57.747 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution. Consult the manufacturer for approved alternate part numbers.
