I have a question about single-port mode of dual DAC.
Could you show me the answer of following problem.
For example AD9741,AD9743,AD9745,AD9746,AD9747,
In the case of using these dual DACs with single-port mode and only DAC1,
how should I do IQSEL pin ?
1. Open with setting ONEPORT = 0
That is, as we select dual-port mode, the IQSEL input is ignored.
2. Connect it to VDD
Always DAC1 is selected.
3. I/Q frame signal of FPGA
I am waiting for your reply.
