QTM216J-100.000MDJ-T

Overview

The QTM216J-100.000MDJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a nominal frequency of 100 MHz. It functions as a standard XO (Crystal Oscillator) with low electromagnetic interference characteristics. The device requires a supply voltage of 1.8V and supports an enable/disable control function. It features a frequency stability of ±50ppm and operates within a temperature range of -40°C to 105°C. The maximum supply current is 22mA. The component is housed in a compact 4-SMD, No Lead package.

Feature Summary

• CMOS output with low EMI specifications
• Enable/Disable control functionality
• Surface mount construction in a 4-SMD no lead package

Applications

• General digital signal processing systems
• Communication equipment requiring precise timing
• Embedded systems utilizing 1.8V logic levels

Procurement Notes

Verify the specific suffix 'MDJ' against official QST documentation to confirm the 1.8V supply voltage and 100MHz frequency parameters. Ensure the ordering part number matches the exact electrical specifications required for the target application, as minor suffix variations may indicate different voltage or temperature ratings.

Selection Notes

Select this component when a 100MHz clock source is required for 1.8V logic circuits. Consider the ±50ppm stability requirement and the -40°C to 105°C operating range. The 4-SMD no lead package is suitable for high-density PCB layouts. Confirm that the 22mA maximum current consumption aligns with the system's power budget.

Part Context

This oscillator belongs to the QTM216J series from QST, designed for applications needing reliable timing signals. The series typically offers various frequencies and voltage options. This specific model provides a 100MHz output, distinguishing it from lower-frequency variants like the 16MHz or 8.192MHz versions found in the same product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires matching the 100MHz frequency, 1.8V supply, 4-SMD package, and ±50ppm stability specifications.
