18QHTF21-13.5545-PD

Overview

The 18QHTF21-13.5545-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5545 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface mount assembly.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact 4-SMD No Lead surface mount package

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 13.5545 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency is critical. Verify that the operating temperature range meets your environmental conditions prior to integration into the final product design.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series offers various frequencies within a small form factor. Mercury Electronics has a long history in manufacturing quartz crystals, providing reliable timing solutions for electronic applications requiring stable frequency generation.

Replacement Considerations

Direct substitutes include other models from the same 18QHTF21 series with different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-68.085-PD, provided the frequency difference is acceptable. Cross-referencing with other manufacturers requires matching the LVCMOS output, 1.8V supply, and 4-SMD No Lead package dimensions.
