Procurement Notes

Verify that the specific ordering suffix matches the required frequency tolerance and temperature range specifications. Confirm package type compatibility with PCB footprints before integration. Ensure supply voltage requirements align with system design constraints. Check for lead-free compliance if environmental regulations apply to the final product assembly process.

Selection Notes

Select this component when a 133 MHz reference signal is required for CMOS-based digital circuits. Consider the ±50ppm stability requirement against system jitter budgets. Evaluate the 3.3V operating voltage against available power rails. Assess the enable/disable feature necessity for power management strategies in the target application design.

Part Context

This part belongs to the QTM750 series of quartz crystal oscillators from QST. The series offers various frequency options within a standardized 7.0x5.0mm SMD package.
