18QHTF21-7.200-PD

Overview

The 18QHTF21-7.200-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.2 MHz and utilizes LVCMOS output logic levels. 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 with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated standby mode for power reduction
• Compact surface-mount package design

Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers
• Digital communication interfaces requiring stable clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. 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. Check for any specific operating temperature range limitations defined in the official datasheet to ensure reliability under your environmental conditions.

Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for 7.2 MHz applications. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the power-down feature if battery life or thermal management is a critical design constraint. Compare alternative frequencies within the same series if the exact 7.2 MHz requirement can be adjusted.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard XO options in a 2.0x1.6 mm package. The series typically supports multiple frequencies and voltage levels, providing designers with flexible timing solutions for space-constrained electronic devices.

Replacement Considerations

Direct substitutes may include other 18QHTF21 variants with different frequencies but identical pinouts and electrical characteristics, such as the 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application.
