ADS4449: Can ADS4449 use only one clock to collect A.B.C.D data?

Hello:

     Can ADS4449 use only one clock to collect A.B.C.D data?Because CLKOUTABM/P and CLKOUTCDM/P are the same clock source, if the printed circuit board traces are the same length, can this be done? Thank you

    User,

    The max skew from CLKOUTCD to CLKOUTAB is about 0.3ns. With the min data valid setup and hold time after CLKOUTxxP zero-crossing (0.6ns for each) it may be possible. The device does provide options to shift the output data which will help with meeting timing if needed. You will have to verify if the device capturing the data can meet these requirements.  

    Regards,
