QTM216-48.000MBE-T

Overview

The QTM216-48.000MBE-T is a standard CMOS quartz oscillator manufactured by QST, operating at a frequency of 48 MHz. It features a 3.3V supply voltage with enable/disable functionality and offers a frequency stability of ±50ppm. The device utilizes a 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. It supports an operating temperature range of -40°C to 85°C and draws a maximum supply current of 10mA. The output type is CMOS, designed for surface mount installation in compact electronic applications requiring precise timing signals.

Feature Summary

• Integrates low EMI phase modulation capabilities within a compact 2016 SMD ceramic package to reduce electromagnetic interference without external components.
• Features a dedicated control pin (Pin 1) that allows software-selectable switching between standard clock mode and low EMI mode via GPIO connection.
• Provides wide voltage compatibility supporting 1.8V, 2.5V, and 3.3V supplies to adapt to various platform requirements.

Applications

• High-definition security camera systems requiring EMC compliance
• Consumer display interfaces utilizing MIPI or LVDS connections
• Wearable devices with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering from distributors. Confirm the operating temperature grade matches the application environment, as variants exist for industrial ranges up to 125°C. Ensure the enable/disable pin configuration aligns with the host microcontroller's GPIO capabilities for optimal EMI management during design integration.

Selection Notes

Select this component for designs where EMC certification challenges arise from standard crystal oscillators. It eliminates the need for additional filtering components like ferrite beads and capacitors, reducing BOM cost and PCB area. Choose based on the required frequency stability and supply voltage compatibility with the target system architecture.

Part Context

This part belongs to the QTM216 series of low EMI CMOS oscillators from QST. The series is characterized by its small 2.0x1.6 mm footprint and integrated spectrum spreading technology. It serves as a direct replacement for larger traditional oscillators in modern compact electronics, offering improved signal integrity and reduced radiated emissions.

Replacement Considerations

Direct substitutes include other QTM216 series variants with different frequencies such as QTM216-24.000MBE-T or QTM216-40.000MBE-T. Cross-reference pinouts and electrical specifications carefully when replacing with generic 2016 package oscillators to ensure functional compatibility.
