18QHTF21-25.050-OE

Oscillators Overview

The 18QHTF21-25.050-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.05 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 with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Generates a precise 25.05 MHz clock signal using LVCMOS logic levels
• Operates on a single 1.8V power supply rail
• Features integrated enable and disable functionality for power management
• Utilizes a small form factor 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for digital logic circuits
• Data communication interface synchronization
• Consumer electronics timing applications

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific RoHS or environmental compliance certifications required for the application.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 25.05 MHz frequency. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the enable/disable pin if power conservation during idle states is necessary. The small 2.0x1.6mm package is ideal for space-constrained designs compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage XO solutions. The series typically offers various frequencies within the same physical footprint. Mercury Electronics specializes in quartz crystals and oscillators, providing frequency control products for industrial and consumer markets since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 25.05 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
