The clock period is referred to as T in the electrical specifications. The time for T is always in nS. Timing specifications can be
given in terms of T. For example, 2T+5 nS
Specification values are not tested.
Specification values listed are for maximum frequency of operation.

Clock Input and Output Timing Specifications
AC timing specifications may be subject to change during ongoing
qualification.
AC timing specifications assume maximum output load capacitance on all
output pins including SDCLK. If this value is different, the input and output
timing specifications would need to be adjusted to match the clock load.
AC timing specifications referenced to SDCLK assume SDRAM control
register bit 3 is 0. After reset this bit is set.
