QTM252-49.152MBE-T

Overview

The QTM252-49.152MBE-T is a standard clock oscillator manufactured by QST Products, LLC. It operates at a frequency of 49.152 MHz with a CMOS output signal type. The component utilizes a surface-mount package measuring 2.5x2.0 mm. It supports a supply voltage of 3.3V and maintains a frequency stability of +/-50 ppm across an operating temperature range of -40°C to +85°C. The device is RoHS compliant.

Feature Summary

• Generates precise 49.152 MHz timing signals using CMOS technology
• Designed for compact electronic assemblies via small SMD footprint
• Operates reliably within industrial temperature ranges

Applications

• Embedded system clock generation
• Data communication interface synchronization
• Industrial control unit timing

Procurement Notes

Verify the manufacturer designation as QST Products, LLC, distinct from other brands utilizing similar nomenclature. Confirm the specific suffix 'BE' aligns with the required 3.3V supply and +/-50 ppm stability specifications. Ensure the package dimensions match the 2.5x2.0 mm requirement for PCB layout compatibility. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 49.152 MHz reference is required for CMOS-compatible logic circuits. The 3.3V supply voltage makes it suitable for modern low-power digital systems. Consider the +/-50 ppm stability for applications requiring moderate precision. The small 2.5x2.0 mm package aids in space-constrained designs compared to larger crystal oscillators.

Part Context

This part belongs to the QTM252 series of quartz ceramic oscillators. These components are designed to replace discrete crystal resonator circuits by providing a ready-made clock signal. The series offers various frequencies and voltage options, with the B-series typically indicating 3.3V operation and E-series denoting specific stability or voltage variants.

Replacement Considerations

Direct substitutes include the TA-49.152MBE-T from TXC Corporation, which shares the same frequency and package form factor but uses MEMS technology instead of quartz. Other compatible replacements must match the 49.152 MHz frequency, 3.3V supply, and 2.5x2.0 mm SMD package dimensions.
