QTM216E-20.000MDM-T

Overview

The QTM216E-20.000MDM-T is a low EMI CMOS oscillator from QST, operating at a nominal frequency of 20 MHz. It features a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 x 0.76 mm. The device supports a supply voltage of 1.8 V and offers an enable/disable function. It provides a frequency stability of ±50 ppm over the industrial temperature range of -40°C to +125°C. The output signal is CMOS, suitable for digital clock distribution applications requiring minimal electromagnetic interference.

Feature Summary

• Integrated phase modulation capability to reduce electromagnetic interference emissions
• Compact surface-mount ceramic package designed for space-constrained layouts
• Single-pin control interface for enabling or disabling the low EMI mode

Applications

• High-definition video transmission systems
• Embedded display interfaces such as MIPI and LVDS
• Security camera modules
• Wearable electronic devices

Procurement Notes

Verify the specific suffix against official QST documentation to confirm voltage levels and tolerance grades. Ensure the ordering code matches the required frequency and package type. Confirm that the supplier provides valid traceability documents. Check for any regional compliance certifications required for the target market. Validate the lead time directly with authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when strict electromagnetic compatibility limits must be met without adding external filtering components. The integrated phase modulation feature allows software-controlled emission reduction via a single GPIO pin. The wide temperature range supports operation in harsh industrial environments. The small footprint facilitates dense PCB routing in portable consumer electronics.

Part Context

This model belongs to the QTM216E series of low EMI oscillators manufactured by QST. The series utilizes quartz crystal technology within a ceramic SMD housing. Other variants in the family offer different frequencies and supply voltages while maintaining the same physical dimensions and functional architecture for system consistency.

Replacement Considerations

Direct substitutes include other QST models within the QTM216E series with matching frequencies. Cross-brand replacements require verification of pinout compatibility and electrical parameters. Ensure alternative sources support the same enable/disable logic and package dimensions.
