3QHTF57-26.2144-PD

Oscillators Overview

The 3QHTF57-26.2144-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 26.2144 MHz and utilizes LVCMOS output logic. The device requires a 3.3V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output logic interface
• Standby mode support for power down
• Compact 4-SMD no lead package

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and control functionality. Confirm that the 'PD' suffix corresponds to the Standby (Power Down) feature rather than Enable/Disable variants. Ensure compatibility with 3.3V logic levels and LVCMOS requirements before integration.

Oscillators Selection Notes

Select this component when a precise 26.2144 MHz reference is required with low-power standby capabilities. Consider the 4-SMD footprint for space-constrained designs. Verify that the LVCMOS output swing matches the input requirements of the downstream circuitry.

Oscillators Part Context

This part belongs to the QHTF57 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 3QHTF57 variant specifically denotes the 3.3V supply version within this family.

Oscillators Replacement Considerations

Direct substitutes include other 26.2144 MHz LVCMOS oscillators in 4-SMD packages. Cross-reference pinouts and electrical specifications carefully. Alternative models may differ in standby control polarity or operating temperature ranges.
