QTM750-50.000MDE-T

Overview

The QTM750-50.000MDE-T is a standard CMOS quartz oscillator manufactured by QST. It operates at a frequency of 50 MHz with a supply voltage of 1.8 VDC. The device features a frequency stability of ±50 ppm and functions within an operating temperature range of -40°C to +85°C. It utilizes a surface-mount package with dimensions of 7x5x1.3 mm and includes a load capacitance specification of 12 pF.

Feature Summary

• Generates a precise 50 MHz clock signal using CMOS output logic.
• Operates on a low 1.8V power supply for energy efficiency.
• Provides stable timing performance across industrial temperature ranges.

Applications

• Digital signal processing systems requiring precise clock synchronization
• Communication equipment utilizing standard CMOS interfaces
• Embedded control units in consumer electronics

Procurement Notes

Verify the specific suffix 'D' against official QST documentation to confirm the 1.8V supply requirement, as variations exist within the QTM750 series. Ensure the selected component matches the required 50 MHz frequency and ±50 ppm stability specifications for your circuit design. Cross-reference the package dimensions and pinout with your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a 1.8V supply voltage is mandatory for the system architecture. Compare against the MBE variant if a 3.3V supply is available, as electrical characteristics may differ. Confirm that the CMOS output swing is compatible with the receiving logic inputs of the target application without additional level shifting.

Part Context

This part belongs to the QTM750 family of surface-mount quartz oscillators from QST. The series offers various frequencies and supply voltages, including 1.8V and 3.3V options. The QTM750-50.000MDE-T specifically denotes the 50 MHz frequency, 1.8V operation, and standard CMOS output configuration within this product line.

Replacement Considerations

The QTM750-50.000MBE-T serves as a direct alternative if the system requires a 3.3V supply instead of 1.8V. Verify pin compatibility and output voltage levels when substituting. Other QTM750 variants may require re-evaluation of power consumption and interface compatibility.
