QTM532-50.000MBA-T

Overview

The QTM532-50.000MBA-T is a standard clock oscillator manufactured by QST, designed for surface-mount applications. It features a 5.0x3.2 mm package and operates on a 3.3V supply voltage. The device utilizes quartz technology to generate a nominal frequency of 50.000 MHz. It provides a frequency stability of ±25 ppm within the specified operating temperature range. The component is RoHS compliant and lead-free, ensuring environmental safety standards are met for modern electronic assemblies.

Feature Summary

• Generates precise 50 MHz clock signals using quartz resonance
• Compact 5.0x3.2 mm surface-mount footprint for space-constrained designs
• Operates at a standard 3.3V supply voltage
• Maintains ±25 ppm frequency stability across the operational temperature range

Applications

• General digital system clock generation
• Embedded microcontroller timing references
• Communication interface synchronization

Procurement Notes

Verify that the ordering suffix 'B' corresponds to the required ±25 ppm stability specification for your specific application environment. Confirm the 3.3V logic compatibility with your target circuitry. Ensure the 5.0x3.2 mm land pattern matches your PCB design guidelines. Check for RoHS compliance documentation if required by your regulatory framework.

Selection Notes

Select this component when a fixed 50 MHz frequency is required with moderate stability needs. The ±25 ppm tolerance suits most general-purpose digital logic applications. Consider the 3.3V operating voltage to ensure compatibility with low-power CMOS families. The small form factor makes it suitable for dense board layouts where larger oscillators cannot fit.

Part Context

This part belongs to the QTM532 series of standard quartz oscillators from QST. The series offers various frequencies and stability options in a consistent 5.0x3.2 mm package. The 'A' or 'B' suffix typically denotes specific stability grades, distinguishing it from higher precision TCXO or VCXO variants in the broader product line.

Replacement Considerations

Cross-reference with other manufacturers offering 50 MHz XO in 5032 packages. Verify pinout compatibility and electrical parameters such as drive level and load capacitance before substitution.
