(3) The Dynamic Specifications are ensured for room to hot ambient temperature only (25°C to 85°C). Refer to the plots of the dynamic
performance vs. temperature in Typical Characteristics to see typical performance from cold to room temperature (–40°C to 25°C).
(4) The Fs/2 spur was removed from all the dynamic performance specifications.
(5) Typical dynamic performance is only tested at Fin = 498 MHz; other input frequencies are specified by design and / or characterization
and are not tested in production.
