QTM216E-38.400MBM-T

Overview

The QTM216E-38.400MBM-T is a low EMI CMOS oscillator operating at 38.4 MHz with a ±50 ppm frequency stability. It features a 3.3V supply voltage and utilizes a 4-SMD, no lead ceramic package measuring 2.0 x 1.6 x 0.76 mm. The device supports an enable/disable function via Pin 1 for phase modulation control, allowing users to switch between standard clock mode and low EMI mode to reduce electromagnetic interference peaks.

Feature Summary

• Integrated low EMI functionality through phase modulation control without external components
• Ultra-thin SMD ceramic package suitable for compact electronic designs
• Wide supply voltage compatibility including 1.8V, 2.5V, and 3.3V options
• Industrial temperature range support up to 125°C

Applications

• HD Camera systems
• DVR (Digital Video Recorder) applications
• Consumer electronics requiring EMC compliance
• Display interfaces such as MIPI or LVDS

Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and supply voltage configuration required for your design. Ensure the selected variant matches the thermal requirements of your application environment. Cross-reference the datasheet specifications against your system's timing constraints before finalizing procurement decisions.

Selection Notes

Select this component when space constraints require a thin profile and strict EMI limits must be met without adding passive filtering. Consider the enable pin utility if dynamic EMI management is needed during operation. Verify that the 38.4 MHz frequency aligns with the target interface protocol requirements for jitter and stability.

Part Context

This part belongs to the QTM216E series of low EMI oscillators from QST. The series is designed to address common EMC certification challenges in consumer and industrial electronics by integrating spectrum spreading capabilities directly into the oscillator package, eliminating the need for additional circuitry.

Replacement Considerations

Direct substitutes include other variants within the QTM216E family with different frequencies or voltages, such as QTM216E-24.000MBM-T or QTM216E-25.000MBM-T, provided the electrical parameters match the design requirements.
