Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output frequency configuration matches the design requirements, as the part supports multiple discrete frequencies. Confirm that the LVPECL output interface is compatible with the target load circuitry. Ensure the 3.3 V supply voltage and current consumption limits are within the system power budget. Check the 8-SMD package dimensions against the PCB footprint specifications to guarantee proper mechanical fit and soldering compatibility.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when precise quad-frequency selection is required within the specified range. Consider the ±20 ppm stability requirement against system jitter tolerance. Evaluate the LVPECL output drive capability against downstream receiver inputs. Compare the 130 mA maximum current draw with available power resources. Verify the -40°C to +85°C industrial temperature range meets environmental operating conditions.
