I have bought a VC707 and a DAQ2 board, , but the project for vc707 have not finish, how long should I wait?
That will be a false interpretation. The design does NOT support full bandwidth on both carriers. I don't think we have even attempted to test this -- since we have no way to change the sampling frequencies. We have recently added a DAC buffer (equivalent to the ADC buffer) to the design, however our software team hasn't got a chance to get to that yet.
If you want to proceed your own-- I suggest you move the FIFO to the DAC side and try adjusting the sampling rate to match the bandwidth.
Can you tell us please what did you try and did not work?
With ZC706，the DAC on DAQ2 can not work at AWG mode，I just try to driver the AD9144 at full speed.
What is AWG mode? Some kind of a waveform? If you are using our reference design-- there is nothing special about VC707 over ZC706. That is -- you can NOT do anything more than ZC706.
AWG means arbitrary waveform generator, On zc706, when load dac buffer, the screen is scrambled and I think that is DDR bandwidth limited, the HDMI controller read/write DDR3, the DAC buffer also read DDR3，I think this problem can be solved when implement on VC707, VC707 work in console mode without hdmi output，so the DDR bandwidth can be fully used by DAC buffer.
