18QHTF21-3.110-OE

Oscillators Overview

The 18QHTF21-3.110-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 3.11 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an active-low enable/disable control pin for power management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific suffix 'OE' indicates the enable feature when sourcing replacements. Confirm the operating voltage requirement matches the target circuit design, as this unit specifies 1.8V operation. Ensure the footprint matches the 2.0x1.6 mm SMD no-lead package dimensions to guarantee proper board integration and soldering reliability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and an enable pin is required for power optimization. The small 2.0x1.6 mm form factor suits space-constrained designs. Verify that the LVCMOS output swing aligns with the input thresholds of the receiving logic gates to ensure signal integrity across the operating temperature range.

Oscillators Part Context
