Please let me know about minimum SCLK cycle time of AD5781 at readaback mode.
Datasheet says below at table4 timing characteristics.
t1 = 28 ns min : SCLK cycle time
t1= 60 ns min: SCLK cycle time (readback mode)
In attached readback mode timing diagrame of AD5781,
which Is minimum SCLK cycle time at first 24 sclk cycle (red circle) 28ns or 60ns ?
