25QHTF22-153.449-PD

Oscillators Overview

The 25QHTF22-153.449-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 153.449 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 2.5V and includes a standby power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm. This component is designed for applications requiring precise timing signals within a small form factor.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct interfacing with digital circuits
• Features a low-profile 4-SMD no-lead surface mount package
• Supports standby mode to reduce power consumption during idle periods

Oscillators Applications

• General clock generation for embedded systems
• Timing reference for data communication interfaces
• Synchronization sources for consumer electronics

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the power-down capability and 'OE' variants may differ in packaging or availability. Ensure the 2.5V supply requirement matches the target circuit design. Confirm the 4-SMD footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a 153.449 MHz frequency is strictly required. Consider the 2.5V operating voltage constraint against available system rails. The small 2.5x2.0mm package is suitable for space-constrained designs. Verify that LVCMOS output swing is compatible with the receiving logic levels.

Oscillators Part Context

This part belongs to the 25QHTF22 series from Mercury Electronics, which specializes in quartz crystal oscillators. The manufacturer has decades of experience in frequency control products. The series typically offers various frequencies and packages to meet diverse timing requirements in modern electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 153.449 MHz frequency, 2.5V supply, LVCMOS output, and 4-SMD package. Check datasheets for pin compatibility and thermal characteristics. Alternative parts from other manufacturers require verification of electrical parameters and mechanical dimensions.
