QTM216-33.33330MBE-T

Overview

The QTM216-33.33330MBE-T is a low EMI CMOS oscillator manufactured by QST, designed for compact electronic applications. It operates at a nominal frequency of 33.3333 MHz and supports supply voltages of 1.8V, 2.5V, and 3.3V. The device features a 4-SMD, no lead ceramic package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.81mm. It offers a frequency stability of ±50ppm and functions within a temperature range of -40°C to +85°C. The maximum supply current is 10mA, and it includes an enable/disable control function via Pin 1.

Feature Summary

• Integrates low EMI phase modulation functionality directly into the component to reduce electromagnetic interference without external filtering components.
• Features a dedicated control pin that allows switching between standard clock mode and low EMI mode via GPIO logic levels.
• Utilizes a thin SMD ceramic seam-sealed package suitable for space-constrained designs such as wearable devices and SiP modules.
• Supports wide voltage operation across 1.8V, 2.5V, and 3.3V rails with tolerance for voltage fluctuations.

Applications

• High-definition security camera systems requiring EMC compliance
• Smartwatch and wearable device clock sources
• Mobile phone internal clock generation
• Portable consumer electronics with strict size constraints

Procurement Notes

Verify the specific suffix 'MBE' against the manufacturer's official datasheet to confirm the exact frequency tolerance, output waveform characteristics, and packaging configuration. Ensure the selected variant matches the required operating temperature range and supply voltage profile for the target application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when design constraints require a small form factor combined with low electromagnetic interference performance. It is suitable for projects where adding external filters is impractical due to PCB space or cost limitations. Consider the ±50ppm stability and 10mA current consumption relative to system power budgets and timing accuracy requirements.

Part Context

This model belongs to the QTM216 series of low EMI oscillators from QST. The series is characterized by its integration of spread-spectrum capabilities in a miniature 2016 package. It targets markets demanding high reliability and reduced noise in digital signal processing and communication interfaces.

Replacement Considerations

Direct substitutes must match the 2016 footprint, 33.3333 MHz frequency, and low EMI functionality. Verify compatibility of control pin logic levels and supply voltage ranges before substitution.
