ADS6425 I/O timing specifications.
The data sheet, ( http://focus.ti.com/lit/ds/symlink/ads6425.pdf ) on page 7 has a note “Timing parameters are measured at the end of a 2 inch pcb trace (100-Ω characteristic impedance) terminated by RLand CL.” We have considered 2 different ways to interpret this. I would assume that the 2 inch trace length is applicable to both the clock and the data, other people have posulated that this might be just on the data line.
Which, if either, is the correct interpretation?
