18QHTF21-37.500-OE

Oscillators Overview

The 18QHTF21-37.500-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 37.5 MHz. It utilizes LVCMOS output logic and supports a supply voltage range typically associated with the 1.8V enable/disable control feature found in this series. The component is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications. This specific model provides precise timing signals suitable for digital systems requiring stable clock references.

Oscillators Feature Summary

• Integrates an enable/disable control function for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Features a leadless SMD package for automated assembly

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Digital signal processing circuits
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the exact supply voltage specifications and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V enable pin configuration aligns with the system's control logic levels to ensure proper operation and standby functionality.

Oscillators Selection Notes

Select this component when a 37.5 MHz reference is required alongside active power-down capabilities. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions and thermal relief requirements specified in the mechanical drawings to maintain reliability.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series is characterized by its ability to operate with enable pins, distinguishing it from continuously running models within the same product family.

Oscillators Replacement Considerations

Direct substitutes must match the 37.5 MHz frequency, LVCMOS output, and 4-SMD no-lead package. Verify equivalent electrical parameters such as phase noise and stability if replacing with components from other manufacturers.
