QTM216E-33.333MDM-T

Overview

The QTM216E-33.333MDM-T is a low EMI CMOS oscillator from QST, operating at a fixed frequency of 33.333 MHz. It features a compact 2016 SMD ceramic package measuring 2.0 x 1.6 x 0.76 mm. The device supports a supply voltage range of 1.8V to 3.3V and operates within an industrial temperature range of -40°C to +125°C. Frequency stability is specified at ±50 ppm. A key functional parameter is the RMS phase jitter, which remains ≤1ps in phase modulation mode, ensuring high clock precision for sensitive digital interfaces.

Feature Summary

• Integrated phase modulation capability reduces electromagnetic interference by spreading the clock spectrum without external components.
• Pin1 control allows software-selectable switching between standard clock mode and low EMI mode via logic level input.
• Ultra-thin 2016 surface-mount package design facilitates integration into space-constrained mobile and wearable devices.
• Wide supply voltage compatibility supports diverse platform architectures ranging from low-power microcontrollers to standard logic levels.

Applications

• High-definition video transmission systems requiring precise clock synchronization
• Mobile consumer electronics with strict PCB area limitations
• Automotive infotainment and display interface modules
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific frequency tolerance and temperature grade against project requirements before ordering. Confirm that the Pin1 configuration matches the host controller's GPIO capabilities for enabling phase modulation. Ensure the 2016 package footprint aligns with the PCB layout guidelines provided in the official datasheet to prevent soldering defects.

Selection Notes

Select this component when EMI compliance is critical and board space is limited. The integrated phase modulation eliminates the need for additional filtering components, reducing BOM cost. Choose based on the required supply voltage and operating temperature range. Verify that the ±50 ppm stability meets the timing constraints of the target interface protocol.

Part Context

This part belongs to the QTM216E series of low EMI oscillators designed for compact applications. The suffix '33.333MDM-T' indicates the specific output frequency, package type, and tape-and-reel packaging format. It is engineered to replace traditional crystal oscillators that require external EMI suppression circuits.

Replacement Considerations

Substitute parts must match the 2016 package dimensions and 33.333 MHz frequency. Verify compatible supply voltages and pin configurations, particularly Pin1 functionality for phase modulation control. Ensure equivalent frequency stability and temperature ranges are maintained for system reliability.
