18QHTF21-80.566406-OE

Overview

The 18QHTF21-80.566406-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 80.566406 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes quartz technology for frequency stability

Applications

• General clock signal generation in electronic circuits
• Embedded systems requiring precise timing references
• Digital communication interfaces

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before procurement. Ensure the 1.8V supply voltage aligns with your design constraints. Confirm that the 4-SMD no-lead package footprint matches your PCB layout specifications to avoid assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific high-frequency clock signal near 80.57 MHz. Consider the small 2.0x1.6 mm form factor for space-constrained designs. Evaluate the need for enable/disable control if power efficiency during idle states is a priority for the application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small footprint, catering to modern electronics that demand miniaturization and reliable clock sources. The 'OE' suffix likely denotes a specific ordering or packaging variant defined by the manufacturer.

Replacement Considerations

Direct substitutes may include other 80.566406 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package from different manufacturers, provided pinouts and electrical characteristics match. Verify equivalent frequency stability and load capacitance requirements when considering alternative brands.
