18QHTF21-16.275-PD

Oscillators Overview

The 18QHTF21-16.275-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.275 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. 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 logic for digital interface compatibility
• Integrated standby mode to reduce power consumption
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded systems requiring low-power oscillators

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 16.275 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint is compatible with the PCB layout. Check datasheet details for tolerance and stability requirements before finalizing the component selection for production.

Oscillators Selection Notes

Select this component when a standard LVCMOS oscillator is required at 16.275 MHz. The 1.8V operating voltage makes it suitable for low-voltage digital circuits. The standby feature provides flexibility for power-sensitive designs. Consider the 4-SMD package size for space-constrained applications. Verify environmental specifications against operational temperature ranges.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates the presence of a power-down or standby control pin, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 16.275 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength. Cross-reference with similar Mercury Electronics models like the 18QHTF21-16.367673-PD if frequency adjustments are permissible.
