i am a little bit in trouble with the HMCAD1511 evaluation board. I am using this board connected to my Zedboard and i want to generate the 1GHz sampling clock on board.
Since the Zedboard i have is not capable of creating such signal, i want to solder the PLL chip on the HMCAD1511 board. I searched on the Hardware User Guide of the board
(here is the link to the document: https://www.analog.com/media/en/technical-documentation/evaluation-documentation/hardware-users-guide-140-00036-00-15xx.pdf)
and in the part list is only referred as "do not mount" component.
Does anyone have the complete part list for the board? it will really save me time.
Thanks for the help.
i had time to search for the piece i was missing. The clock generator used on the HMCAD1511 board is the Texas instruments CDCE421A.

Hope someone can take advantage of this information, thanks anyway ;)
Hello Kratos, i am confused if the bandwidth of HMCAD1511 is up to 300MHz when use one channel mode, could you help me?
Hi Ihjhit !
I am a little bit confused by the question but i'll try to answer.
When you want to sample at 1 Gbps with this chip, you have to feed it with an external 1 GHz clock. That said, if you are using the single channel mode at 1G the chip uses all 4 internal ADC interleaved (so each of them is sampling at 250 MHz with a known phase shift wrt to the others). So in the fastest mode that the chip can handle the max sample frequency that the single ADC handle is 250M but the whole throughput will be 250M x 4.
Hope this solve your doubt.
