QTM532-48.000MBE-T

Overview

The QTM532-48.000MBE-T is a standard clock oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 48 MHz with a CMOS output signal type. The device features a frequency stability of ±50 ppm and requires a supply voltage of 3.3 V DC. It is housed in a compact 5.0 x 3.2 mm SMD package with a maximum height of 1.2 mm. The component supports an operating temperature range from -40°C to +85°C and holds AEC-Q100 qualification for automotive reliability standards.

Feature Summary

• AEC-Q100 qualified for automotive electronic applications
• CMOS output signal generation
• Compact 5.0 x 3.2 mm surface-mount footprint

Applications

• Automotive embedded systems
• Industrial automation controllers
• General electronics timing circuits

Procurement Notes

Verify the specific manufacturer designation, as some sources list TXC Corporation while others cite QST or QST Products LLC. Confirm the exact package dimensions and electrical parameters against the official datasheet provided by the supplier. Ensure the component meets the required AEC-Q100 standards if used in automotive contexts. Cross-reference the ordering suffixes to guarantee compatibility with the intended circuit design.

Selection Notes

Select this oscillator when a 48 MHz CMOS clock source is required for space-constrained designs. The ±50 ppm stability suits general timing needs rather than high-precision synchronization. Consider the 3.3 V supply requirement and ensure the PCB layout accommodates the 5.0 x 3.2 mm package size. Verify thermal performance within the -40°C to +85°C range for the target environment.

Part Context

This component belongs to the QTM532 series of quartz crystal oscillators. The series offers various frequencies and stability options within a standardized small outline package. These devices are engineered to provide stable clock signals for microprocessors, memory, and communication interfaces in modern electronic assemblies.

Replacement Considerations

The QTM532-48.000MBE-T may be substituted with other 48 MHz CMOS oscillators in the same 5.0x3.2mm package. Ensure replacement parts match the 3.3V supply, ±50ppm stability, and AEC-Q100 qualification if automotive use is required.
