QTM216-40.000MBE-T

Overview

The QTM216-40.000MBE-T is a standard CMOS oscillator manufactured by QST, operating at a frequency of 40 MHz. It utilizes a crystal base resonator and supports a supply voltage of 3.3V with enable/disable functionality. The device is housed in a compact 4-SMD, no lead package measuring 2.0x1.6 mm. It offers a frequency stability of ±50ppm and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated low electromagnetic interference (EMI) design reduces the need for external filtering components.
• Phase modulation control via Pin 1 allows switching between standard clock mode and EMI reduction mode.
• Compact 2.0x1.6 mm SMD ceramic package suitable for space-constrained applications.

Applications

• High-definition video transmission systems requiring precise clock synchronization.
• Consumer display interfaces such as MIPI and LVDS.
• Security camera modules and embedded vision systems.
• Wearable devices and smart watches with strict size limitations.

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the manufacturer source, as this component may be produced by TXC Corporation under license or distribution agreements. Ensure the required frequency stability and temperature range match the target application environment before finalizing procurement.

Selection Notes

Select this model for applications requiring a 40 MHz clock in a minimal footprint. It is suitable for designs needing flexible EMI management through GPIO-controlled phase modulation. Consider the ±50ppm stability for general digital interfaces. Evaluate power consumption requirements against the typical operating current specifications provided in the datasheet.

Part Context

This part belongs to the QTM216 series of low EMI CMOS oscillators from QST. The series includes various frequencies and voltage options, all sharing the same 2016 package dimensions. It is designed to replace traditional crystal oscillators that require additional filtering to meet EMC standards.

Replacement Considerations

Direct substitutes include other QTM216 variants with different frequencies or voltages if system timing allows. Cross-reference with TXC Corporation equivalents for identical pinout and electrical characteristics. Verify package compatibility and thermal performance when substituting.
