(1) 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 Performance Plots to see typical performance from cold to room temperature (-40°C to 25°C).
(2) These measurements were taken in Extended Control Mode (ECM) with the DES Timing Adjust feature enabled (Addr: 7h). This feature
is used to reduce the interleaving timing spur amplitude, which occurs at fs/2-fin, and thereby increase the SFDR, SINAD and ENOB.
(3) 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.
