QTM750P-100.000MBE-T

Overview

The QTM750P-100.000MBE-T is a standard clock oscillator manufactured by QST, designed for high-frequency digital applications. It operates at a nominal frequency of 100 MHz with a stability of ±50 ppm across the industrial temperature range of -40°C to +85°C. The device utilizes LVPECL output format and requires a single 3.3V DC power supply. Housed in a compact 6-SMD, No Lead package measuring 7.0mm x 5.0mm x 1.3mm, it integrates quartz crystal technology within a ceramic body. This component provides precise timing signals suitable for data communication systems and high-speed processing circuits.

Feature Summary

• Generates stable 100 MHz timing signals using integrated quartz crystal technology
• Features LVPECL output format optimized for high-speed digital interfaces
• Operates reliably within the extended industrial temperature range of -40°C to +85°C
• Utilizes a compact surface-mount package for efficient PCB layout integration

Applications

• High-speed data communication equipment requiring precise clock synchronization
• Network infrastructure devices utilizing LVPECL interface standards
• Industrial control systems operating in extreme environmental conditions
• Telecommunications hardware demanding low phase noise performance

Procurement Notes

Verify the specific suffix 'BE' against official manufacturer documentation to confirm the exact output configuration and voltage compatibility. Ensure that the receiving circuitry supports the LVPECL signal levels provided by this oscillator. Cross-reference the package dimensions and pinout with the target design specifications to guarantee mechanical fit and electrical connectivity before finalizing procurement orders.

Selection Notes

Select this component when a 100 MHz frequency is required alongside LVPECL outputs for superior signal integrity in high-speed designs. Consider the ±50 ppm stability specification for applications sensitive to timing jitter. Evaluate the 3.3V supply requirement against available system voltages. The compact SMD form factor makes it suitable for space-constrained layouts where traditional through-hole oscillators cannot be accommodated.

Part Context

This part belongs to the QTM750P series of standard oscillators from QST, which are engineered for robust performance in demanding electronic environments. The series typically offers various frequency options while maintaining consistent package dimensions and electrical characteristics. The P-series designation often indicates specific packaging or enable features compared to standard variants, providing designers with flexibility for different application requirements.

Replacement Considerations

The QTM750P-100.000MBD-T serves as a potential substitute within the same product family, though verification of the output suffix difference is mandatory. Ensure that any replacement maintains the LVPECL output format and identical frequency stability specifications. Confirm that the physical footprint remains compatible with existing PCB footprints to avoid rework.
