18QHTF21-75.595-OE

Overview

The 18QHTF21-75.595-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.595 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise clock signals in space-constrained electronic systems.

Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable functionality for power control
• Compact surface-mount package design

Applications

• General purpose clock generation
• Embedded system timing references
• Consumer electronics devices

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to ensure reliable operation under your environmental conditions.

Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a specific 75.595 MHz frequency. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6 mm footprint if board space is limited. The enable pin feature allows for dynamic power management strategies in battery-operated or energy-efficient designs.
