• 关于AD9785-DPG2-EBZ评估板

    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-DPG2-EBZ和AD9627-150EBZ 这两款评估板

    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…

  • The output observed on the pins OUT1_P/OUT1_N/OUT2_P/OUT2_N of AD9785 is always high before and after programming.

    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…

  • RE: AD9788SPI通讯无应答

    IO电压满足CMOS要求

    芯片手册:

    All data input is registered on the rising edge of SCLK. All data

    is driven out of the AD9785/AD9787/AD9788 on the falling

    edge of SCLK.

    数据在SCLK上升沿寄存,在下降沿改变,应该也没问题

  • Getting pixel data from the ADV7611 into a DAC

    Sirs:

    I am using an ADV7611 HDMI receiver and the output bus is connected to a ADV7125 DAC.  Unfortunately the ADV7125 will not interface with the differential IQ lines to my ADL5375 modulator.

    May I substitute an AD9785 or a AD9776A for the ADV7125…

  • RE: Help Selecting a suitable DAC.

    What kind of performance do you need from the DAC? For high performance applications, you would not typically use the FPGA as the clock source for the DAC since there are better performance clock sources available, such as ADI's ADF series of PLLs.…
