18QHTF21-25.152-PD

Oscillators Overview

The 18QHTF21-25.152-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.152 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports standby or power-down functionality for energy management
• Utilizes LVCMOS output logic for digital interface compatibility
• Encapsulated in a small form factor 4-SMD no lead package

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a 25.152 MHz clock source is required with low voltage operation. Consider the 1.8V supply constraint and the need for standby control. Evaluate the physical size constraints due to the 2.0x1.6 mm package. Compare performance metrics such as phase noise and stability if available in the technical documentation against system requirements.

Oscillators Part Context

This part belongs to the QHTF series of surface mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar small packages. The 'PD' suffix indicates the inclusion of power down functionality, distinguishing it from standard continuous operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 25.152 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics with alternative manufacturers before integration.
