18QHTF21-25.200-OE

Oscillators Overview

The 18QHTF21-25.200-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.2 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Integrates enable/disable functionality for active power management
• Delivers stable LVCMOS clock signals for digital circuits
• Utilizes a low-profile surface-mount package design

Oscillators Applications

• Embedded system clock generation
• Consumer electronics timing references
• Industrial control unit synchronization

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 25.2 MHz reference is required for low-voltage digital interfaces. The integrated enable pin makes it suitable for battery-powered applications requiring power conservation. Consider the small 2.0x1.6mm form factor for space-constrained designs where standard through-hole oscillators cannot fit within the available board area.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for general-purpose timing applications. The manufacturer specializes in quartz-based frequency control products, including crystals and oscillators. This specific model represents a standard fixed-frequency solution rather than a programmable or temperature-compensated variant, targeting cost-sensitive mass production environments.

Oscillators Replacement Considerations

Direct substitutes include other 25.2 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pin compatibility and voltage levels when cross-referencing. Alternative part numbers may exist within the same family but require confirmation of identical electrical characteristics and physical dimensions.
