QTM532-75.000MDE-T

Overview

The QTM532-75.000MDE-T is a standard CMOS quartz oscillator manufactured by QST Products, LLC. It operates at a frequency of 75 MHz with a supply voltage of 1.8V and offers a frequency stability of ±50ppm across an operating temperature range of -40°C to +85°C. The device features an enable/disable function and draws a maximum supply current of 20mA. It is housed in a compact 4-SMD, no lead package measuring 5.00mm x 3.20mm with a maximum seated height of 1.40mm.

Feature Summary

• Integrated enable and disable functionality for power management control
• CMOS output signal generation from quartz resonator source
• Surface mount construction in a small form factor package

Applications

• General clock signal distribution in electronic circuits
• Timing reference sources for digital logic systems
• Embedded system clock generation modules

Procurement Notes

Verify the manufacturer designation as QST Products, LLC when sourcing this component. Confirm that the specific suffix corresponds to the 1.8V supply voltage variant and the 75 MHz frequency requirement. Ensure compatibility with the specified 4-SMD no-lead footprint dimensions during PCB layout review.

Selection Notes

Select this oscillator when a low-voltage 1.8V CMOS clock source is required. The ±50ppm stability rating suits general timing applications within the industrial temperature range. Consider the physical dimensions of the 5.00mm x 3.20mm package against available board space constraints.

Part Context

This component belongs to the QTM532 series of surface-mount crystal oscillators. The series includes various frequency options and voltage levels, such as 3.3V variants. The QTM532-75.000MDE-T specifically denotes the 75 MHz frequency, 1.8V operation, and CMOS output type within this product family.

Replacement Considerations
