18QHTF21-58.6231-PD

Overview

The 18QHTF21-58.6231-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 58.6231 MHz with an LVCMOS output signal format. The device functions at a supply voltage of 1.8V and includes a standby or power-down control feature for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise clock generation.

Feature Summary

• Provides stable LVCMOS clock signals at 58.6231 MHz
• Operates on a single 1.8V power supply
• Includes standby mode for power reduction
• Utilizes a leadless SMD package for board space efficiency

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded microcontroller timing sources
• Consumer electronics timing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 58.6231 MHz frequency. Consider the LVCMOS output compatibility with your receiving logic gates. Evaluate the need for power-down functionality if battery life or thermal management is a priority in the final application environment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from standard continuous-operation variants in the same family.

Replacement Considerations

Direct replacements must match the 58.6231 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure seamless integration without circuit redesign.
