18QHTF21-25.175-OE

Oscillators Overview

The 18QHTF21-25.175-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 25.175 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable pin allows for power management integration within the system design. Consider the small form factor of the 4-SMD package for space-constrained layouts where traditional leaded packages are unsuitable.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile surface-mount oscillators. The series typically offers various frequency options within a standardized package outline. The manufacturer specializes in quartz-based frequency control products, providing timing solutions for consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages with similar frequencies. Verify electrical parameters such as phase noise and jitter if strict timing precision is required. Check pinout compatibility to ensure seamless replacement without PCB redesign.
