16. This frequency indicates the maximum frequency at which the device may operate in data path mode (dedicated input pin to output pin). This assumes data
17. This specification indicates the guaranteed maximum frequency, in synchronous mode, at which an individual output or buried register can be cycle by a clock
18. This parameter indicates the minimum time after a synchronous register clock input that the previous register output data is maintained on the output pin.
