18QHTF21-13.562-OE

Overview

The 18QHTF21-13.562-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 13.562 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control for power optimization
• Surface-mount design with no lead construction

Applications

• General purpose timing reference
• Digital signal processing systems
• Communication equipment clock sources

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the manufacturer's current datasheet to ensure compliance with project requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for any environmental certifications or RoHS compliance status required for the intended application market.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The small 4-SMD footprint makes it appropriate for space-constrained designs. Ensure the operating temperature range meets the environmental conditions of the final assembly, as specifications may vary by grade.

Part Context

This part belongs to the Mercury Electronics XO series, which provides quartz-based timing solutions. Mercury Electronics has been manufacturing frequency control products since 1973, specializing in crystals, oscillators, and filters. This specific model represents their standard output oscillator line designed for general electronic applications.

Replacement Considerations

Direct substitutes must match the 13.562 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before substitution. Consult the manufacturer's cross-reference list for approved alternatives.
