18QHTF21-19.995-OE

Oscillators Overview

The 18QHTF21-19.995-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 19.995 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• Consumer electronics timing circuits
• Portable device clock generation
• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury documentation to confirm exact electrical tolerances and temperature range specifications. Ensure the 1.8V supply requirement matches the target circuit design before procurement. Confirm package orientation and pinout details from the manufacturer datasheet to prevent assembly errors during SMT placement processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output format. The small 2.0x1.6mm footprint makes it appropriate for space-constrained portable designs. Consider the enable/disable feature if power efficiency is critical for the application environment compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators produced by Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. The -OE suffix indicates specific packaging or testing configurations defined by the manufacturer for this particular frequency variant.

Oscillators Replacement Considerations

Direct substitutes include other 19.995 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin compatibility and enable functionality when cross-referencing with alternative manufacturers' components.
