18QHTF21-80.330-OE

Overview

The 18QHTF21-80.330-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 80.33 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a 1.8V supply voltage. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This surface-mount oscillator is suitable for space-constrained electronic designs requiring precise clock signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable pin functionality for power management
• Utilizes lead-free SMD packaging for automated assembly

Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. 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. Check for any specific handling instructions regarding electrostatic discharge sensitivity during installation.

Selection Notes

Choose this model when a precise 80.33 MHz clock source is required in a minimal footprint. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The enable/disable feature allows for dynamic power control, which is beneficial for battery-operated or energy-efficient devices. Consider the operating temperature range to ensure reliability under environmental conditions.

Part Context

This component belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small 2.0x1.6mm package. Similar parts in the lineup include different frequency variants such as 50.33 MHz or 37.888 MHz, maintaining consistent electrical characteristics and package dimensions while differing only in their output frequency specifications.

Replacement Considerations

Direct substitutes may include other 80.33 MHz LVCMOS oscillators in a 4-SMD no-lead package. Verify pinout compatibility and supply voltage requirements when cross-referencing. Ensure the replacement part meets the same size constraints and output drive capabilities to maintain board integrity.
