Oscillators Overview

The 18QHTF21-22.400-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 22.4 MHz and utilizes LVCMOS output logic. The device is designed for 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 dimensions of 2.0 x 1.6 mm. This component is suitable for applications requiring precise timing signals in space-constrained electronic designs.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable control functionality
• Utilizes a low-profile 4-SMD no-lead surface mount package

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Communication modules needing stable clock references
• Embedded systems utilizing LVCMOS logic levels

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable pin configuration, as this differs from other variants like 'PD'. Ensure the 1.8V supply voltage requirement aligns with the target system's power rails. Confirm that the 2.0x1.6mm footprint matches the PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on operating temperature ranges or electrical specifications prior to finalizing the bill of materials.

Oscillators Selection Notes

Select this component when a small form factor and low voltage operation are critical. The enable feature allows for power management strategies in battery-operated devices. Compare against similar models in the 18QHTF21 series to ensure the correct output logic and package type meet the design requirements. Consider the manufacturing history of Mercury Electronics as a supplier of frequency control products when evaluating long-term availability and consistency.
