我需要用SPI配置其中的寄存器，但现在不知道数据是应该在上升沿还是下降沿发和收，图比较模糊，datasheet中也没提到，谁有配过，回答一下，谢谢。

Hi,

i'm working with ZC702 and two FMC-cards: AD9739a (Transmitter) and AD9467 (Receiver). The hardware works in general and so i can pretend signals up to 1,25 GHZ directly via cable from AD9739a to AD9467 with the help of ADI IIO Oscilloscope.

When using the FPGA (Zedboard Zynq Evaluation and Development Kit – xc7z0x0clg484-1) to control the AD9517-4(AD9467-FMC board) by SPI protocol in Verilog, I failed to send the command data and read out the registers’ data.

The whole project is with 25MHz…

Hi, I am using AD9517-4 as the clock generator with 10M single ended reference clock. However, I cannot get my PLL locked. So I want to know how to config my loop filter and N/R divider? I also notice that ADclkSim tells the internal VCO can have a range…

I use the FPGA write the 9517-4 registers as follow

I want to get the 9517-4 working as follow simulation.

But I can only get 1550MHz at out0. The out 4,out 6, out 7 go out

a DC signal. the out7 also with a100MHz sine wave.now the sync

pin is empty…

采用10M的参考时钟，需要输出125M的差分电平，但AD9517-4的VCO和PLL没有正常工作。请问VCO和PLL的正常工作需要注意哪些方面？是PLL的配置？或者是外部LOOP FILTER的电路设计需要和PLL的配置相匹配？ 如何做？ 谢谢大家！

I used the LVDS output4&5 of 9517-4, but I found I could not bypass the divider of these channals. I have configed many kinds of clocks with the divider2.1 &divider2.2 on, it's no problem about these.

I have read the datasheet of 9517-4, it…

    我使用的是AD9517-4时钟芯片。有一块板子上当给芯片供电后，无参考时钟输入，也没有配置寄存器，OUT7引脚有信号输出，输出无规律的杂波。此外只有OUT7引脚有信号输出，其它引脚没有。另一块相同电路的板子没有出现这种问题。

     信号如下图所示：

     想请教下大家是否碰到过这种问题，或有没有解决办法。谢谢！

Hi,

On our board we are using AD9517-4 device. the SPI lines are controlled using Xilinx FPGA. after setting it in 4 wire SPI mode the write is happening properly. But whenever we try read operation it happens only one time. after the read operation…

Hi everyone,

I am trying to use a "AD9517/PCBZ (Rev B)" evaluation board to drive an AD9517-0 installed in another board designed by us.

The intention is to use the "AD9516/17/18 Evaluation Software, Version 1.1.0" to control/program the AD9517…
