18QHTF21-18.560-OE

Oscillators Overview

The 18QHTF21-18.560-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 18.56 MHz and utilizes LVCMOS output logic levels. The device is designed for operation with a supply voltage of 1.8V and features an enable/disable control function to manage power consumption. 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 signal compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation for digital circuits
• Timing reference for microcontrollers and processors
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct voltage and package configuration. Confirm that the OE suffix aligns with the required enable pin functionality. Cross-reference the part number with official Mercury Electronics catalogs to validate availability and latest revision status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 1.8V supply voltage is available and an enable control feature is required for power management. The 2.0x1.6 mm footprint is appropriate for space-constrained designs. Ensure the LVCMOS output swing matches the input requirements of the downstream load circuitry without additional level shifting.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronic Industrial Co., Ltd, a manufacturer specializing in quartz frequency control products. The series offers various frequencies and packages, with the 18QHTF21 variant specifically denoting the 1.8V LVCMOS type in a small outline no-lead package.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-18.560-PD, which shares the same electrical specifications but may differ in packaging or suffix designation. Verify pinout and mechanical dimensions before substitution.
