QTM750-133.000MDE-T

Overview

The QTM750-133.000MDE-T is a standard CMOS crystal oscillator manufactured by QST, operating at a frequency of 133 MHz. It utilizes a surface-mount package with dimensions of 7.00 mm x 5.00 mm and a height of 1.3 mm. The device functions on a 1.8V supply voltage and offers a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C. It features a lead-free and RoHS-compliant construction suitable for automated assembly.

Feature Summary

• CMOS output signal generation for digital logic interfacing
• Surface-mount design compatible with automated pick-and-place processes
• Industrial temperature range operation ensuring reliability in varied environments

Applications

• High-speed data communication interfaces requiring precise clocking
• Embedded systems utilizing microprocessors or FPGAs
• Network equipment and telecommunications infrastructure

Procurement Notes

Verify that the specific part number suffix matches the required voltage and enable/disable functionality, as variations exist within the QTM750 series. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the ordering quantity aligns with the manufacturer's minimum order requirements and packaging specifications before finalizing procurement.

Selection Notes

Select this component when a 133 MHz clock source is required with low power consumption due to its 1.8V operation. Consider the 7x5mm footprint for PCB layout constraints. Compare against other series members if different voltage levels or enable pin configurations are needed, as the 'D' suffix typically denotes specific electrical characteristics distinct from 'B' variants.

Part Context

This oscillator belongs to the QTM750 series of standard quartz oscillators designed for compact electronic applications. The series provides various frequency options and voltage levels, maintaining consistent physical dimensions to facilitate board design flexibility. It serves as a critical timing reference for synchronizing data transmission in modern digital circuits.

Replacement Considerations

Direct substitutes may include other 133 MHz CMOS oscillators in the same 7x5mm package. Verify equivalent electrical parameters such as supply voltage, load capacitance, and stability. Cross-reference with QTM750-133.000MBE-T only if 3.3V operation and enable/disable functionality are acceptable alternatives.
