Hi,

I have a AD9785 Evaluation Board. I connect USBto PC and run ACE software , it recognize board but in state it write State = Unkown and i can't  reset or program it;

Whenever I am probing the output on L1,L2,L3,L4 connected to the pins OUT1_P,OUT1_N,OUT2_P,OUT2_N it always shows 3.3V before and after programming. I have cross checked every connection as per the reference schematic and nothing was changed significantly…

您好！今天刚收到在贵公司买的AD9785-DPG2-EBZ评估板，之前说会附赠评估板的电路原理图，怎么没有收到电路原理图了？

关于AD9785评估板：

（1）EVAL-DPG 数据模式发生器(DPG)高速DAC评估平台

   （2）DPG2 - Data Pattern Generator (DPG) High-Speed DAC Evaluation Platform

您好！我买的AD9785-DPG2-EBZ和AD9627-150EBZ 这两款评估板是否可以通过背板连接线连在一起实验。即将模拟信号经过我的这个AD评估板，然后直接经过DA评估板，转换为原来的模拟信号？这个方案可行吗？如果可以的话，应该怎么连接这两个板子的连接器件将这两个板子连接在一起了？如果不可以的话，原因是什么了？

另外一个问题：对于AD9627这款评估板（绿色的），背板连接器的输出信号是哪些引脚了？同样，对于AD9785这款评估板（蓝色的），背板连接器哪些引脚是输入信号？也就是这两块板子的背板连接器该如何连接起来了…

Hi

The purpose is to apply DAC(AD9785) differential output signals to the I/Q mixer (HMC1056LP1BE), and in this design, balun should be used to convert the differential signal to single-ended and then apply to the mixer (HMC1056LP1BE).

HELLO

I have a evaluation board  EVAL-AD9785 for testing in 2 GHz with ADL5375 modulator and IQ modulator HMC1056LP1BE and EVAL-HMC765LP6CE for testing in 8 GHz.

when I use  EVAL-AD9785 and connect output to the spectrum  in 2.4GHz and we can see spectrum and…
