18QHTF21-16.500-OE

Oscillators Overview

The 18QHTF21-16.500-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.5 MHz and utilizes LVCMOS output compatibility. The device supports a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• Timing and clock signal generation in electronic devices
• High-performance application circuits
• Consumer electronics requiring low-power oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output format. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor for space-constrained layouts. Verify availability of the specific 16.5 MHz frequency variant as part numbers are frequency-specific within this series.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-footprint quartz crystal oscillators. The series typically offers various frequencies and voltage options, including 3.3V variants like the 3QHTF21-PD. The 'OE' suffix indicates the presence of an output enable function, distinguishing it from basic continuous-output models.

Oscillators Replacement Considerations

Direct substitutes must match the 16.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check datasheets for equivalent parts from other manufacturers offering identical pinout and electrical characteristics to ensure seamless integration without redesign.
