Tool/software:
I'm looking into the ADC3643 datasheet and have a couple of questions about the timing that provided in this file. First of all tcd (as an example -0.7 ns) is shown as a negative number and I don't understand dos my data is happening before the rising edge of the dclk by (for example 0.7 ns) or my rising edge of the clk happens prior to data by 0.7 ns? Also, does the sum of data valid and tcd should be equal to the clk_period/2? or it's doesn't matter and data an go over the falling edge of the clk ?
