18QHTF21-13.234375-PD

Overview

The 18QHTF21-13.234375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.234375 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic interface
• Standby (Power Down) functionality
• Compact 4-SMD No Lead package

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm that the Standby pin configuration matches the system control logic to ensure proper power-down operation during idle states.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The 4-SMD No Lead package is suitable for space-constrained designs. Verify that the 13.234375 MHz frequency meets the specific timing needs of the application, as other frequencies are available within the same series.

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 indicates the inclusion of a Power Down feature, distinguishing it from models without standby capabilities. This series is designed for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical 1.8V LVCMOS specifications and Standby functionality, provided the frequency matches exactly. Cross-reference with Mercury Electronics documentation for equivalent packages and electrical characteristics.
