-Let's see now how we can change the sampling rate to 1.24 GHz. The AD9680 maximum sampling rate is 1.25GHz. However the board uses a 80MHz crystal as the reference clock to AD9528. Unless you change it, this limits the maximum clock output on the banks to 1.24GHz. Also note that the Kintex 7 SOC on ZC706 is a -2 device. The maximum lane rate is limited to 10Gbps. However, it should be possible to over clock the transceiver (but do so at your own risk). Officially, you must get a -3 device to run the link at 12.4Gbps. +Here is the ILA plot screen capture
