25QHTF21-161.13258-PD

Oscillators Overview

The 25QHTF21-161.13258-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 161.13258 MHz and utilizes LVCMOS output logic levels. The device requires a 2.5V supply voltage and features a standby or power-down function to reduce consumption when inactive. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Integrates a standby mode for active power management
• Provides stable LVCMOS signal outputs
• Utilizes a leadless surface-mount form factor

Oscillators Applications

• Digital communication systems requiring precise clocking
• Data acquisition equipment
• Network infrastructure components

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 2.5V supply rail is stable within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions precisely to avoid soldering defects during assembly.

Oscillators Selection Notes

Choose this component when a fixed 161.13258 MHz reference is required with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the operating temperature range and physical size constraints of the target application to ensure proper integration into the electronic assembly.

Oscillators Part Context

This model belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series is characterized by its use of quartz crystal technology for frequency stability. The 'PD' suffix typically indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 161.13258 MHz frequency, 2.5V supply, and LVCMOS output type. Verify pinout compatibility for the 4-SMD No Lead package. Cross-reference with other Mercury QHTF models or industry-standard equivalents that offer identical electrical specifications and thermal performance ratings.
