18QHTF21-13.3375-PD

Overview

The 18QHTF21-13.3375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.3375 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby function for power down capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Standard XO configuration with LVCMOS output interface
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific RoHS or environmental compliance certifications required by your project specifications.

Selection Notes

Select this component when a stable 13.3375 MHz reference is needed with low power consumption. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the standby feature if power efficiency is critical. Verify that the operating temperature range meets your environmental conditions. Compare size constraints against other available packages in the series.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies including 51.2 MHz, 75.385 MHz, and 75.57 MHz. All variants share similar electrical characteristics and packaging, differing primarily in their output frequency specifications.

Replacement Considerations

Direct substitutes include other 13.3375 MHz LVCMOS oscillators in 4-SMD packages. Verify pinout compatibility and voltage levels. Cross-reference with Mercury Electronics' full catalog for alternative frequencies if exact match is unavailable.
