18QHTF21-48.896-PD

Oscillators Overview

The 18QHTF21-48.896-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 48.896 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports standby mode for power down
• LVCMOS output logic compatibility
• Compact 4-SMD no lead package design

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific datasheet for exact electrical parameters including frequency stability and load capacitance requirements before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD package footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS interface compatibility is required. The standby feature makes it suitable for power-sensitive designs. Consider the operating temperature range and package dimensions relative to space constraints in the final assembly to ensure reliable performance under intended environmental conditions.

Oscillators Part Context

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

Oscillators Replacement Considerations

Direct substitutes include other 48.896 MHz LVCMOS oscillators with 1.8V operation and compatible pinouts. Verify equivalent specifications for frequency tolerance and phase noise if replacing with components from different manufacturers.
