  • AD6657 synchronous capture problem

    Hi,

    I am using for a sensor array the AD6657 AD converter evaluation board together with the HSC-ADC-EVALCZ FPGA based capture board.

    I would have two questions for my specific application:

    • I need to sample the four channels synchronously to evaluate…

  • AD6657 digital outputs


    Hi. I am currently working on AD6657 quad IF receiver. Can the part output data to its ports in parallel (portA and portB at the same time/ CHA and CHC or CHB and CHD) since channels A and B share the same output pins as well as for channels C and D…

  • AD6657 + HS_ADC_EVALC Problem. Please Help

    Please help me regarding the problem i am facing..... Thank you in advance for your time and effort....

    -> I have a EVALC board and a AD6657EBZ baord. Both are connected, powered from respective power adapter, and connected to my PC using USB cable.…

  • RE: AD6655的驱动问题

    上电之后，直接测量DCOA的输出是75MHz，改变分频比之后，DCOA输出还是75MHz，这是什么原因 啊？

    可以确定的：

    1、评估板没有问题，刚刚拿到手的

    2、时钟配置是选择的板上晶振（Y1）来为器件提供时钟输入，该添加和移除的电阻都已经完成

    3、控制器是选用的MSP430单片机，3个引脚分别和评估板的SPI电路中的CSB、SCLK、SDI管脚连接，J1的2、3脚，J2的2、3脚和J21分别用跳帽连接

    我想知道，通过测量DCOA管脚的输出来判断控制程序是否写进AD6655，对不对？配置程序是按照AD6657的修改的…
