Procurement Notes
Verify the specific part number suffix to ensure compatibility with required frequency tolerance and temperature range specifications. Confirm that the LVPECL output type matches the receiving circuitry requirements. Check RoHS compliance documentation if environmental regulations apply to the final product assembly. Ensure the 3.3V supply voltage aligns with the system power design before procurement.
Selection Notes
Select this component when a 122.880 MHz VCXO with LVPECL outputs is required. Consider the 3.3V operating voltage and the need for an enable pin during system design. Evaluate the 5.00mm x 3.20mm footprint against available board space. Compare stability requirements against other QST VCXO models if different frequency or tolerance needs arise.
Part Context
This model belongs to the QST QTV series of voltage controlled crystal oscillators. The series offers various frequencies and output types. The QTV532P variant specifically denotes the package style and electrical characteristics. QST Products specializes in timing solutions for digital applications. This part represents a standard offering for mid-range frequency applications.
Replacement Considerations
Direct substitutes may include other QST VCXOs with identical 122.880 MHz frequency and LVPECL output. Verify pinout compatibility and package dimensions before swapping. Alternative manufacturers may offer similar specifications but require careful evaluation of electrical parameters. Ensure any replacement maintains the same enable/disable functionality and supply voltage requirements.
