18QHTF21-25.0008-PD

Oscillators Overview

The 18QHTF21-25.0008-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.0008 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features a standby (power down) control function. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications.

Oscillators Feature Summary

• LVCMOS output logic interface
• Standby power down control capability
• Compact 4-SMD no lead package

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the exact part number against official manufacturer documentation to ensure compatibility with specific voltage and control requirements. Confirm that the 1.8V supply and standby functionality align with the target design specifications before procurement.

Oscillators Selection Notes

Select this component when a 25.0008 MHz clock source with LVCMOS outputs is required. Ensure the design supports 1.8V operation and utilizes the standby control feature if power management is necessary. Verify package dimensions fit the PCB layout constraints.

Oscillators Part Context

This model belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The suffix PD indicates the presence of a standby or power-down control pin, distinguishing it from models without this feature.

Oscillators Replacement Considerations

Direct substitutes include other 25.0008 MHz LVCMOS oscillators with 1.8V supply and standby control in a 4-SMD no lead package. Verify electrical parameters and pinout compatibility before substitution.
