tsu(C16–FS)
Setup time, sixteenth negative SCLK edge after FS low on which bit D0 is sampled before
rising edge of FS
10
ns
tsu(C16–CS)
Setup time. The first positive SCLK edge after D0 is sampled before CS rising edge. If FS
is used instead of the SCLK positive edge to update the DAC, then the setup time is between
the FS rising edge and CS rising edge.
