18QHTF21-62.800-OE

Overview

The 18QHTF21-62.800-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 62.8 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable control functionality
• Utilizes a leadless SMD package for surface-mount assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded system clock inputs

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. The enable/disable feature allows for power management optimization in battery-operated devices. Consider the physical size constraints of the 4-SMD package when evaluating board space limitations for high-density designs.
