• Includes power-down standby capability to reduce consumption
• Designed for surface-mount applications with a leadless package

Applications

• General-purpose clock generation in electronic circuits
• Timing reference for digital systems requiring 95.573 MHz
• Portable devices utilizing low-voltage operation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD No Lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 95.573 MHz timing source is required with low-voltage compatibility. The LVCMOS interface suits standard digital logic families. Consider the power-down feature if battery efficiency is critical. Verify environmental compliance and operating temperature range suitability for the intended application environment.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down control pin or function, allowing the oscillator to be disabled when not in use to save power.

Replacement Considerations

Direct replacements must match the 95.573 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent electrical characteristics and pinout compatibility. Consult official substitution lists from Mercury Electronics for validated alternatives.
