3QHTF57-40.665-PD

Oscillators Overview

The 3QHTF57-40.665-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 40.665 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 3.3V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions suitable for surface-mount assembly.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports standby power-down mode to reduce operational consumption
• Utilizes a leadless SMD package design for automated surface-mount processing

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontroller and FPGA circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 3.3V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package specifications to guarantee proper solder joint formation and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a precise 40.665 MHz timing reference is required with low-power standby capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the operating temperature range and package size constraints relative to the available board space and thermal environment of the final application.

Oscillators Part Context

This part belongs to the 3QHTF57 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small form factor. The -PD suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same product family.

Oscillators Replacement Considerations

Direct substitutes include other 40.665 MHz LVCMOS oscillators in 4-SMD packages with compatible 3.3V operation and pinout configurations. Verify equivalent electrical parameters such as phase noise and jitter specifications to ensure signal integrity is maintained in the replacement scenario.
