QTM216E-33.333MBM-T

Overview

The QTM216E-33.333MBM-T is a low EMI CMOS oscillator manufactured by QST, operating at a nominal frequency of 33.333 MHz. It features a compact SMD ceramic package with dimensions of 2.0 x 1.6 x 0.76 mm. The device supports a supply voltage of 3.3V and draws a maximum supply current of 10mA. Frequency stability is specified at ±50ppm over the operating temperature range of -40°C to +125°C. It includes an enable/disable function for power management and incorporates spread spectrum technology to reduce electromagnetic interference.

Feature Summary

• Integrates spread spectrum clocking functionality within a miniature surface-mount package to minimize electromagnetic emissions without external filtering components.
• Features a dedicated control pin for enabling or disabling the output signal, allowing for flexible power management and system synchronization.
• Utilizes CMOS output levels compatible with standard digital logic interfaces, ensuring reliable signal integrity in high-speed data transmission applications.

Applications

• High-definition video display interfaces requiring precise timing signals
• Embedded systems with strict electromagnetic compatibility requirements
• Industrial control equipment operating in wide temperature environments

Procurement Notes

Verify the specific suffix codes on the ordering part number to confirm the exact frequency tolerance, temperature grade, and packaging configuration. Ensure that the selected variant matches the required supply voltage and output load specifications for the target application circuit. Cross-reference the manufacturer's latest datasheet to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when space constraints necessitate a small footprint combined with low EMI performance. The ±50ppm stability suits most digital communication protocols. Consider the 3.3V supply requirement and ensure the host system can accommodate the 10mA current draw. Verify that the industrial temperature range meets the environmental conditions of the deployment site.

Part Context

This model belongs to the QTM216E series of low EMI oscillators from QST Products. The series is designed to replace traditional crystal oscillators in applications where electromagnetic interference is a critical concern. The family offers various frequencies and packages, providing designers with options for different size and performance needs while maintaining consistent low-noise characteristics.

Replacement Considerations

Direct substitutes include other QTM216E variants with matching frequencies, such as QTM216E-38.400MBM-T or QTM216E-27.000MBM-T, provided the frequency difference is acceptable for the system design. Ensure any replacement maintains the same package dimensions and pinout configuration to guarantee mechanical compatibility.
