Procurement Notes
Verify the specific ordering suffix against official QST documentation to ensure correct frequency and package configuration. Confirm that the LVPECL output type matches system requirements. Check RoHS compliance status if environmental regulations apply. Ensure the enable pin logic level aligns with the host controller's voltage domain. Validate the operating temperature range suitability for the intended deployment environment.
Selection Notes
Select this component when a precise 133.330 MHz clock signal is required with LVPECL compatibility. Consider the 7.0x5.0 mm footprint for PCB layout constraints. Evaluate the +/-50 ppm stability against system jitter tolerance requirements. Ensure the 3.3V supply voltage is available on the target board. Verify thermal management capabilities for the -40°C to +85°C operational range.
Part Context
This part belongs to the QTM750P series of quartz oscillators from QST. The series typically includes various frequencies and packages. The 'P' suffix often denotes specific package or performance variations within the family. This model represents a standard XO variant optimized for general-purpose high-frequency timing applications.
Replacement Considerations
Direct substitutes may include other QST models within the QTM750P series with compatible frequencies. Cross-brand replacements require matching LVPECL output, 3.3V operation, and similar footprint dimensions. Verify electrical parameters such as phase noise and stability before substitution.
