• ad9173

    您好,我在fpga中采用spi通信读ad9173寄存器时,发现ad9173没有响应。其中spi通信速率为10M完全满足datasheet不大于80M的要求。其中通信方式采用四线制。读取寄存器为0x000. ila抓取的信号如图所示:

    spi通信只控制了spi通信的四根线。ss_n为片选、miso 从机(ad9173)输出主机(fpga)输入、mosi主机(fpga)输出从机(ad9173)输入、sclk0串行时钟线。

    能告诉我ad9173为啥没有响应,正确的配置ad9173步骤吗?

  • AD9173 DAC TPL core input format

    Hi

    I removed DMA+FIFO and want to feed both DACs with IQ data from my own DSP core. With original DDS it looks good, but not with my DSP. Datawidth 256bit and rate 250MHz matches together.

    What do I need to configure and how do I need to map the 256bits…
