AD9959: Data valid time

Hi

 

Unfortunately I do not understand exactly the Timing Specification for serial I/O port in the data sheet.

As indicated on page 31 of 44 the SDO data is clocked out on the falling edge of SCLK.

 

The data SDO changes after the falling edge of SCLK after the Data valid time (t DV).

 

This time (t DV) may change over all devices (process variation) and over environment conditions.

So normally there is a specification for the fastest and for the slowest time (t DV).

 

May you give me explicitly the exact values for the fastest and for the slowest data valid time?

 

Thanks

Rolf
