18QHTF21-102.000-PD

Overview

The 18QHTF21-102.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 102 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Utilizes LVCMOS output interface

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

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 package footprint matches your PCB layout specifications to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a 102 MHz reference signal is required with low-power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency during idle states is a critical design constraint for the target application environment.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small form factor. The series typically provides standard XO options with power-down functionality. Other variants in this line include different frequencies such as 51.2 MHz and 80 MHz, maintaining consistent package and voltage characteristics.

Replacement Considerations

Direct substitutes may include other 102 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative manufacturers' components to ensure seamless integration without redesigning the host board.
