18QHTF21-20.0025-OE

Oscillators Overview

The 18QHTF21-20.0025-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fundamental frequency of 20.0025 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an active enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable pin for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with space constraints
• Industrial control modules needing stable oscillation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this model when a 20.0025 MHz clock source is strictly required for synchronization tasks. Consider the LVCMOS output swing if interfacing with 3.3V logic without level shifting. Evaluate the enable/disable feature necessity for battery-operated devices where power efficiency is critical compared to always-on oscillator alternatives.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages within a small form factor. The 'OE' suffix indicates the presence of an output enable control pin, distinguishing it from basic oscillator variants that lack power management capabilities.

Oscillators Replacement Considerations

Direct substitutes must match the 20.0025 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable pin configuration, to ensure seamless integration without PCB redesign.
