QTM216J-50.000MBJ-T

Overview

The QTM216J-50.000MBJ-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 50 MHz. It utilizes CMOS output with low electromagnetic interference characteristics and functions within a 3.3V supply voltage range. The device offers a frequency stability of ±50 ppm and supports an enable/disable control function. It is designed for operation across an extended temperature range of -40°C to +105°C, with a maximum supply current of 22 mA. The component is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm.

Feature Summary

• Compact 2.0x1.6mm surface-mount footprint suitable for space-constrained designs
• CMOS output interface with low electromagnetic interference emissions
• Integrated enable/disable control functionality for power management
• Extended industrial temperature rating from -40°C to +105°C

Applications

• Digital signal processing systems requiring precise clock sources
• Communication equipment utilizing serial data transmission interfaces
• Embedded controller boards needing stable timing references
• Industrial automation modules operating in varied thermal environments

Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and load capacitance specifications. Confirm that the package variant corresponds to the designated tape-and-reel or cut-tape packaging format required for automated assembly processes. Ensure compatibility with the target system's voltage levels and thermal constraints before finalizing procurement orders.

Selection Notes

Select this component when a small form factor oscillator is required alongside strict electromagnetic interference limits. The 3.3V supply requirement aligns with standard logic families, while the ±50 ppm stability suits most synchronous digital applications. Consider the enable pin utility if dynamic power saving is necessary during idle periods in the host system design.

Part Context

This part belongs to the QTM216 series of low EMI oscillators from QST. The series provides various frequency options within the same physical envelope. The J suffix typically denotes specific performance parameters such as load capacitance or stability variations compared to other variants in the lineup.

Replacement Considerations

Direct substitutes include other QTM216 series parts with identical pinouts but different frequencies, such as QTM216J-48.000MBJ-T. Cross-brand replacements require verification of pin compatibility, voltage levels, and output waveform characteristics to ensure functional equivalence.
