Deserializing a DDR signal

Jacob Putz

Other Parts Discussed in Thread: ADS62P29I am designing a system around the ADS62P29. The outputs of the ADC essentially have a DDR LVDS setup in which when the clock is high Dn is output on the pins and when the clock is low, Dn+1 is output. What component would be best to separate out the Dn and Dn+1 values of the signal?

    This should be a simple enough thing to integrate into whatever you are using to process the data - an FPGA? - if I were to do it with discrete logic, I would latch the word with one falling edge of the CLK, then latch the entire word (both the ADS62P9 and the latch output) when the CLK is high.
