Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure exact electrical parameter alignment, particularly regarding frequency tolerance and load capacitance requirements. Confirm that the 4-SMD no-lead package footprint matches the target PCB design guidelines. Ensure the supply voltage specification aligns with the system's 3.3V rail availability and noise margins before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 66.666 MHz reference is required with low-power standby capabilities via the enable pin. Consider the ±50ppm stability limit against system jitter requirements. Evaluate the -20°C to +70°C industrial temperature range against environmental conditions. Compare the HCMOS output swing with downstream input thresholds to ensure signal integrity without additional buffering.
