18QHTF21-13.900-OE

Oscillators Overview

The 18QHTF21-13.900-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 13.9 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, specifically sized as SMD2016-4P, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Integrates enable/disable functionality for active power control
• Utilizes a leadless 4-SMD surface-mount package design

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with space-constrained layouts
• Industrial control modules utilizing low-voltage logic

Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct frequency and voltage specifications. Confirm that the required enable/disable pin configuration matches the target circuit design. Check for any updated revision codes or alternative package variants before finalizing procurement orders to avoid component mismatches.

Oscillators Selection Notes

Choose this component when a 1.8V supply rail is available and LVCMOS signaling is required. The small SMD2016 footprint suits applications with strict board area limitations. Ensure the operating temperature range meets environmental requirements. Validate that the enable pin can be properly controlled by the host system to manage power consumption effectively during idle states.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages within a standardized small outline package family. The 18QHTF21 variant specifically denotes the 2.0mm x 1.6mm form factor, distinguishing it from larger packages in the broader product line while maintaining similar electrical characteristics.

Oscillators Replacement Considerations

Direct substitutes include other 13.9 MHz LVCMOS oscillators in 2016 packages from compatible manufacturers. Verify pinout compatibility and voltage tolerance before swapping. Cross-reference datasheets for thermal performance and load capacitance requirements to ensure equivalent circuit behavior.
