gmZAN3 Preliminary Data Sheet
5.2 Preliminary AC Characteristics
The following targeted specifications have been derived by simulation.
All timing is measured to a 1.5V logic-switching threshold. The minimum and maximum operating
conditions used were: T_DIE = 0 to 125° C, Vdd = 1.71 to 1.89V, Process = best to worst, C_L = 16pF for all outputs.

Note: DCLK Clock Adjustments are the amount of additional delay that can be inserted in the DCLK path, in order to reduce the
propagation delay between DCLK and its related signals.
