18QHTF21-16.615-PD

Oscillators Overview

The 18QHTF21-16.615-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.615 MHz and utilizes LVCMOS output logic levels. The device is designed for surface mount applications, featuring a compact 4-SMD, No Lead package configuration. It supports a supply voltage of 3.3V and includes a power-down function via standby mode control. The component is rated for an operating temperature range of -40°C to 85°C with a frequency stability of ±50ppm.

Oscillators Feature Summary

• Standard XO design with LVCMOS output interface
• Integrated power-down capability for energy management
• Compact surface-mount package suitable for space-constrained designs

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Communication interface synchronization modules

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the power-down feature and 3.3V operation when sourcing. Ensure the manufacturer designation matches Mercury Electronics Ind. Co. Ltd rather than other entities like Mercury United Electronics. Confirm package dimensions against mechanical constraints prior to procurement.

Oscillators Selection Notes

Select this component when a low-cost, standard frequency oscillator with power management is required. The 16.615 MHz frequency is specific; verify compatibility with target system clock requirements. Consider the ±50ppm stability limit against system timing tolerance needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The '-PD' suffix typically indicates the inclusion of a power-down pin or function, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-16.615-OE variant, which shares similar electrical characteristics but may differ in packaging or supplier distribution channels. Verify pinout and voltage compatibility before substitution.
