18QHTF21-25.120-OE

Oscillators Overview

The 18QHTF21-25.120-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 25.12 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 LVCMOS output logic for digital interface compatibility
• Features an Enable/Disable pin for active power control
• Utilizes a low-profile surface-mount package design

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 25.12 MHz timing source is required for low-voltage digital circuits. The integrated enable function makes it suitable for battery-operated devices requiring power conservation. Consider the small form factor for space-constrained layouts where traditional through-hole oscillators cannot fit within the design boundaries.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, designed for high-reliability timing applications. The manufacturer specializes in quartz-based frequency control products, including crystals and oscillators. This specific part represents a standard output configuration optimized for modern consumer and industrial electronics requiring stable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 25.12 MHz frequency, LVCMOS output type, and 1.8V operating voltage. Verify that alternative components support the same Enable/Disable functionality and fit the 2.0x1.6mm SMD package. Cross-reference pin assignments to ensure electrical compatibility without redesigning the host circuit board.
