We are planning to use the AD8117, but would like to know about timing characteristics on the serial mode.

Please let me know following some questions.


AD8117/AD8118 datasheet Rev.A

Page 5

On the Table 2. & Figure 2. Timing Diagram, Serial Mode,


Q1)  /CLK pulse width (t2) is 50ns, but CLK Pulse Separation (t4) is 150ns.

       Is it true ? If that is true , why is it ? Can't use 50%/50% duty clk cycle ?

       I think maybe 50ns, t2=t4 ?


Q2)  /CLK to DATA OUT Valid (t7) is 120ns min.

       Is it min value ?

       I think maybe max value ?


Thanking you

With best regards and wishes
