18QHTF21-18.0944-OE

Oscillators Overview

The 18QHTF21-18.0944-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 18.0944 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 with dimensions of 2.0x1.6mm, designed for surface-mount applications.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/Disable control pin
• Compact 4-SMD no-lead package

Oscillators Applications

• General digital circuit timing
• Embedded system clock generation
• Consumer electronics timing references

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical tolerances and lead-free status. Ensure the 1.8V supply requirement matches the target system design. Confirm the 4-SMD no-lead footprint compatibility with PCB assembly processes before ordering.

Oscillators Selection Notes

Select this component when a precise 18.0944 MHz reference is required in space-constrained designs. The 1.8V operation suits low-power systems. The enable/disable feature allows for dynamic power saving. Verify that LVCMOS output swing is compatible with the receiving logic inputs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small 2.0x1.6mm footprint. Mercury Electronics is a specialized manufacturer of quartz crystals and frequency control products based in Taiwan.

Oscillators Replacement Considerations

Cross-reference with other 18.0944 MHz XO parts in the same 4-SMD 2.0x1.6mm package. Ensure identical 1.8V supply voltage and LVCMOS output characteristics. Verify pinout compatibility if substituting with different manufacturers.
