18QHTF21-16.000-PD

Oscillators Overview

The 18QHTF21-16.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 16 MHz and utilizes an LVCMOS output signal format. The device supports a supply voltage of 1.8V and includes a power-down feature for standby mode control. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated power-down functionality for energy management
• Compact surface-mount form factor

Oscillators Applications

• General-purpose clock generation in embedded systems
• Timing reference for microcontrollers
• Digital signal processing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit's power rails. Confirm that the 4-SMD no-lead package dimensions are compatible with the PCB footprint and manufacturing processes to avoid assembly issues.

Oscillators Selection Notes

Select this component when a 16 MHz clock source with low-power standby capability is required. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. Consider the 1.8V operating voltage constraint and verify that the thermal characteristics of the SMD package meet the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies within the standard range, all sharing similar electrical characteristics and packaging. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 16 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if specified in the original design constraints.
