18QHTF21-19.800-OE

Oscillators Overview

The 18QHTF21-19.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 19.8 MHz and utilizes LVCMOS output logic levels. The component requires a 1.8V supply voltage and includes an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/Disable functionality
• Compact 4-SMD No Lead package

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this model when a precise 19.8 MHz reference is required with low-voltage compatibility. The integrated enable/disable feature supports dynamic power saving strategies. Consider the small form factor for space-constrained designs. Verify environmental specifications if operating in extreme temperature ranges.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies with consistent electrical characteristics. The 'OE' suffix typically denotes specific packaging or tape-and-reel options. These components are designed for high reliability in consumer and industrial electronics applications.

Oscillators Replacement Considerations

Direct substitutes must match the 19.8 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Check pinout compatibility and thermal performance. Verify that alternative manufacturers meet the same frequency stability and phase noise specifications.
