QTM216J-27.000MBJ-T

Overview

The QTM216J-27.000MBJ-T is a standard CMOS crystal oscillator manufactured by QST, operating at a nominal frequency of 27 MHz. It functions within a 3.3V supply voltage range and features an enable/disable control interface. The device exhibits a frequency stability of ±50 ppm across the specified operating temperature range of -40°C to +105°C. It utilizes a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm, designed for surface-mount assembly. The maximum supply current is rated at 22 mA, and it meets AEC-Q100 automotive reliability standards.

Feature Summary

• CMOS output signal compatible with standard digital logic interfaces
• Integrated enable and disable functionality for power management
• Automotive-grade reliability compliant with AEC-Q100 standards
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Automotive electronic systems requiring precise timing references
• Industrial control equipment operating in extended temperature environments
• Consumer electronics utilizing 3.3V logic families
• Communication modules needing stable clock signals

Procurement Notes

Verify that the specific suffix MBJ-T corresponds to the 27 MHz frequency and 3.3V operation when sourcing. Confirm the package type matches the 4-SMD (2x1.6) specification required by your PCB layout. Ensure the supplier provides documentation confirming AEC-Q100 compliance if automotive application is intended. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a small form factor oscillator is required for 3.3V systems. The ±50 ppm stability is suitable for general timing applications rather than high-precision RF synthesis. Consider the -40°C to +105C range for harsh environment deployments. The enable pin allows for system-level power optimization during idle states.

Part Context

This model belongs to the QTM216J series of surface-mount oscillators from QST. The series offers various frequency options within a standardized 2.0 x 1.6 mm package. It is designed as a drop-in replacement for larger through-hole or larger SMD oscillators in modern miniaturized circuit boards.

Replacement Considerations

Direct substitutes include other QTM216J series parts with different frequencies but identical packages, such as QTM216J-16.000MBJ-T or QTM216J-30.000MBJ-T, provided the frequency requirement is adjusted accordingly.
