18QHTF21-2.034688-OE

Oscillators Overview

The 18QHTF21-2.034688-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 2.034688 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package with a maximum seated height of 0.031 inches (0.80mm).

Oscillators Feature Summary

• Provides stable timing signals via LVCMOS output interface.
• Includes hardware enable and disable functionality for power management.
• Designed for surface-mount assembly using a leadless SMD package.

Oscillators Applications

• Digital signal processing circuits requiring precise clock synchronization.
• Communication systems utilizing standard frequency references.
• Embedded controller boards needing low-profile timing sources.

Oscillators Procurement Notes

Verify the specific operating temperature range and frequency stability requirements against application needs before ordering. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead footprint matches the PCB layout design to guarantee proper soldering and mechanical retention during assembly processes.

Oscillators Selection Notes

Select this component when a fixed 2.034688 MHz reference is required with minimal board space constraints. Consider the LVCMOS compatibility with downstream logic levels. Evaluate the enable/disable pin utility for power-sensitive designs. Compare against other Mercury QHTF series variants if different frequencies or voltage levels are needed for the same form factor.

Oscillators Part Context

This part belongs to the QHTF series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and voltage options within a consistent small outline package. These components are designed for general-purpose timing applications where size and cost efficiency are prioritized over high-performance stability metrics found in TCXO or OCXO families.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical footprints but different frequencies, such as 18QHTF21-9.465-OE or 18QHTF21-8.300-OE, provided the frequency change is acceptable for the circuit design. Cross-reference with other manufacturers offering 4-SMD LVCMOS oscillators at 2.034688 MHz if supply chain constraints exist.
