18QHTF21-8.200-OE

Overview

The 18QHTF21-8.200-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.2 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an active-low 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 provides precise timing signals suitable for digital circuits requiring stable clock sources.

Feature Summary

• Provides stable 8.2 MHz clock signal generation using LVCMOS logic levels
• Includes active-low enable/disable pin for power management control
• Operates on a single 1.8V supply voltage for low-power applications
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• Digital system clock generation
• Microcontroller timing sources
• Low-voltage embedded circuit synchronization
• Portable electronic device timing

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's datasheet to ensure compatibility with required enable functions and packaging specifications. Confirm that the 1.8V supply voltage aligns with the target system design constraints before procurement. Check for RoHS compliance status if environmental regulations apply to the end product assembly process.

Selection Notes

Select this component when a small footprint and low voltage operation are critical requirements. The LVCMOS output ensures compatibility with standard digital logic families operating at 1.8V. Consider the enable feature if dynamic power saving is necessary. Ensure the 8.2 MHz frequency meets the specific timing needs of the application circuit without requiring additional dividers or multipliers.
