18QHTF21-24.444-OE

Oscillators Overview

The 18QHTF21-24.444-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.444 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features an Enable/Disable control function and is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Provides precise clocking signals via LVCMOS output logic
• Features integrated enable/disable control functionality for power management
• Designed for reliable timekeeping applications

Oscillators Applications

• Reliable clocking systems
• Precise timekeeping circuits
• Embedded digital systems requiring stable frequency sources

Oscillators Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct voltage and package specifications. Confirm that the OE variant matches the required enable/disable functionality. Cross-reference the datasheet for operating temperature ranges and load capacitance requirements before integration into final designs.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 24.444 MHz frequency. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Ensure the application supports LVCMOS logic levels and requires hardware-based enable/disable control rather than software-driven clock gating.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and frequency control products. The series includes various frequencies and packages, catering to diverse electronic component needs for precision timing in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 24.444 MHz LVCMOS oscillators in 4-SMD No Lead packages with 1.8V supply and enable pins. Verify pin compatibility and electrical parameters such as phase noise and stability before substitution.
