18QHTF21-3.250-OE

Oscillators Overview

The 18QHTF21-3.250-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 3.25 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications. The component supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Includes hardware enable/disable control functionality
• Utilizes a leadless SMD package design for automated assembly

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for microcontroller units
• Data communication interface synchronization circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the specified operating temperature range to ensure consistent performance. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official mechanical drawing to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and precise timing accuracy is required for digital interfaces. The enable/disable feature makes it suitable for battery-powered devices requiring power conservation. Consider the ±50ppm stability limit when designing against stricter jitter or phase noise requirements found in high-speed serial protocols.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequency options within a standardized small form factor. These components are designed to replace discrete crystal and buffer combinations, simplifying board layout and reducing component count in consumer electronics and industrial control applications.

Oscillators Replacement Considerations

Direct replacements must match the 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify frequency compatibility with the system clock input. Check if alternative suppliers offer equivalent stability and temperature ranges.
