18QHTF21-3.100-PD

Oscillators Overview

The 18QHTF21-3.100-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 3.1 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Surface-mount 4-SMD no lead package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 3.1 MHz operation. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD no lead package footprint corresponds to the PCB layout specifications before ordering.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The choice depends on the need for a standard XO type with power-down capabilities. Consider the small form factor of the 4-SMD package for space-constrained designs.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF21 series of standard crystal oscillators. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The manufacturer specializes in quartz-based frequency control products.

Oscillators Replacement Considerations

Check for direct substitutes within the same series having identical pinout and electrical characteristics. Verify that alternative parts support the same 1.8V supply and LVCMOS output levels.
