Oscillators Procurement Notes

Verify the specific output configuration (LVPECL) and supply voltage requirements against the target circuit design before procurement. Confirm that the component meets the required frequency stability specifications for the application. Ensure the selected package size fits the available PCB footprint constraints. Check for any recent manufacturer notices regarding product changes or obsolescence status prior to finalizing orders.

Oscillators Selection Notes

Select this component when LVPECL outputs are required for noise immunity in high-frequency applications. Consider the ±50ppm stability requirement relative to system jitter budgets. Evaluate the 88mA current draw against available power rails. Compare physical dimensions against alternative packages if space is limited. Verify compatibility with existing clock distribution networks.
