QTM750-8.000MBE-T

Overview

The QTM750-8.000MBE-T is a standard clock oscillator manufactured by QST Products LLC, designed for surface-mount applications. It operates at a nominal frequency of 8.000 MHz with CMOS output signals. The device utilizes a ceramic package and functions on a 3.3V DC supply voltage. It features a frequency stability of ±50 ppm across an operating temperature range of -40°C to +85°C. The physical dimensions are 7.0mm x 5.0mm x 1.3mm in a 4-SMD, no-lead configuration. This component includes enable/disable control capabilities for power management.

Feature Summary

• CMOS output signal generation for digital logic interfacing
• Integrated enable and disable functionality for power optimization
• Robust ceramic construction ensuring reliability in industrial environments

Applications

• Standard clock distribution in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Procurement Notes

Verify the specific ordering suffix against official QST documentation to ensure correct frequency and tolerance specifications. Confirm that the 4-SMD package matches your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 3.3V supply voltage aligns with your system design constraints before finalizing procurement.

Selection Notes

Select this model when a precise 8 MHz timing source is required for CMOS-based circuits. Consider the ±50 ppm stability specification for applications sensitive to clock drift within the specified temperature range. The compact 7x5 mm footprint makes it suitable for space-constrained designs. Verify that the enable pin functionality meets your power sequencing needs compared to fixed-output alternatives.

Part Context

This component belongs to the QTM750 series of quartz oscillators from QST. The series offers various frequencies and packages, providing standardized timing solutions for commercial and industrial electronics. The MBE suffix typically denotes specific packaging and tolerance characteristics within the product line, distinguishing it from other variants like the MDE series.

Replacement Considerations

Direct substitutes include other 8 MHz CMOS oscillators in 7x5mm SMD packages with similar ±50 ppm stability. Verify pin compatibility and electrical parameters such as supply voltage and current consumption. Cross-reference part numbers from manufacturers like TXC or Abracon for equivalent performance metrics.
