Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to ensure exact electrical parameters match system requirements. Confirm that the HCSL output voltage levels are compatible with the receiving logic inputs. Ensure the PCB footprint matches the 6-SMD no lead package dimensions provided in the mechanical drawings. Check for any required external components such as decoupling capacitors or pull-up resistors as specified in the application notes.

Oscillators Selection Notes

Select this component when a fixed frequency reference near 364.8 MHz is required with adjustable tuning capabilities. The MEMS construction offers superior shock and vibration resistance compared to crystal alternatives. Consider the ±35 ppm stability requirement against system jitter budgets. The 3V supply constraint must align with the overall power architecture. Evaluate the thermal performance within the -40°C to +85°C range for the intended environment.
