18QHTF21-19.6606-OE

Oscillators Overview

The 18QHTF21-19.6606-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 19.6606 MHz and utilizes LVCMOS output logic levels. 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, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Consumer electronics requiring precise frequency references
• Industrial control systems utilizing standard oscillators

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 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a standard LVCMOS oscillator with enable/disable capability is required. The 1.8V operating voltage makes it suitable for low-power portable or battery-operated devices. Consider the 19.6606 MHz frequency specifically for applications needing this exact timing reference rather than standard frequencies like 20 MHz or 25 MHz.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, a manufacturer specializing in quartz crystals and frequency control products. The series typically offers various frequency options within a standardized small outline package format, providing designers with flexibility while maintaining consistent physical dimensions across different model variants.

Oscillators Replacement Considerations

Direct substitutes include other 19.6606 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation and enable pins. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution.
