Re: Differences between : DCM, PLL, MMCM and PMCD

You can find quite a few things by doing the following two google searches:
"dcm pll difference"
"pll mmcm difference"

Those are just the evolution in clock management from DCM to PLL to MMCM in xilinx parts. For that matter, you could check the datasheets for the 6 vs 7 series xilinx devices. In the clocking resources there's tons of info on precisely this.

Re: Differences between : DCM, PLL, MMCM and PMCD

This thread is driving me crazy because this is the top link when I search mmcm vs pll using the Googles.

I think this deserves a reasonable explanation. Anyone else? (I wouldn't be here if I knew the answer)
