What is the maximum output RF bandwidth for AD9164 and AD9174? I would like to see if either of them can generate an RF signal with at least 4 GHz bandwidth. Thanks!
For the case of AD9164, your discussion centers on instantaneous bandwidth (iBW) capability, which is limited by the SERDES interface data rate and lane count of 12.5 GBPS and 8 lanes (100 GBPS of total instantaneous data transfer is possible). If this max available bandwidth of JESD is used, a total of 2.25GHz of complex iBW or 5GHz of real iBW can be achieved. I suggest that you try our remote eval tool to see some of this. It can be found here: http://labs.analog.com/ad916x . This is a live lab set-up accessible over the web. You can try some things on it that may help you understand better.
For the case of AD9174, the JESD lanes can operate at 15.4GBPS, these numbers change to a total of 2.5GHz of complex iBW or 6GHz of real iBW can be achieved.
