Oscillators Procurement Notes

Verify the specific output logic configuration and supply voltage requirements against your system design before procurement. Confirm that the PECL output levels are compatible with the receiving input stages of your target application. Ensure the operating temperature range meets the environmental conditions of the final deployment site. Cross-reference the part number suffixes to confirm the exact frequency tolerance and package variant matches your bill of materials.

Oscillators Selection Notes

Select this component when a stable 83.330 MHz reference signal is required in space-constrained designs. The PECL output is suitable for high-frequency data transmission paths where noise immunity is critical. Consider the ±1.0 ppm stability specification for applications sensitive to long-term drift. Evaluate the 3.3V power requirement against available board rails to ensure proper voltage regulation and current sourcing capabilities are present.
