18QHTF21-44.550-OE

Oscillators Overview

The 18QHTF21-44.550-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 44.55 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Supports active low or high enable/disable control functionality
• Utilizes a leadless SMD package for automated assembly

Oscillators Applications

• Embedded systems requiring stable clock references
• Communication equipment signal processing
• Consumer electronics timing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this component when a 44.55 MHz reference is required with low-voltage operation. Consider the enable pin utility for power-sensitive designs. Compare alternative frequencies within the 18QHTF21 series if different clock speeds are needed while maintaining the same package and electrical characteristics.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various standard frequencies optimized for consumer and industrial electronics. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer's ordering guidelines.

Oscillators Replacement Considerations

Direct substitutes must match the 44.55 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
