• BIST AD9735

    Hi,

    I just received an evaluation board for the AD9735-DPG2-EBZ and i'm trying to perform a BIST test.
    I installed all the software needed to download vectors into the DPG2 and the AD9735_SPI.exe to control the DAC's register from SPI.

    My question…

  • AD9735 LVDS input voltage range

    The input voltage range on the digital LVDS inputs of the AD9735 DAC is specified to be 825 mV min to 1575 mV max.  The absolute maximum voltage rating for these inputs is 3.6 V (DVDD33 + 0.3V).

    We plan to drive these inputs from an FPGA with DC coupling…

  • 如何保证2片AD9735的同步

    我的设计中使用2片DAC(AD9735)产生I和Q基带信号,同时,AD4350产生2.4GHz本振。然后通过正交调制(选用ADL5385),产生载频为1.2GHz的调制信号。2片DAC时钟由AD9516提供600MHz时钟。FPGA为2路DAC输出IQ数据,该数据保存在一片ROM中,从而保证IQ基带信号的严格对起。现在发现,2片AD9735的输出发生错位,错位0~4个DAC时钟周期。而且,每次上电后,错位情况都不一样。但是,上电后,错位保持不变。DAC的配置:每次上电后,同时对AD9735进行硬件复位…

  • Datasheet errors in the AD9736/5/4

    Question 1)
    Is the datasheet 288522419AD9734_5_6_0.pdf the latest version? There seem to be
    pinout errors on page 54 og 68.

    Question 2)
    What connections are reccommended for the 2 unused bits in this 12-bit device?
    I assume I want…
  • Low Latency High-Speed ADC and DAC

    Hi All,

    One of my customer is looking for low latency high-speed ADC and DAC.

    His application is to capture high frequency signal by high-speed ADC and the data is processed by FPGA and output control signal from the FPGA and is converted to high-speed…

  • RE: 超级干货——DAC接口基本原理

    DAC数据输入考虑因素

    最早的单芯片DAC几乎不包含逻辑电路,且数字输入必须维持并行数据,才能维持数字 输出。而今,几乎所有DAC都会被锁存,且只需向其中写入数据,而不用去维持。有些 器件甚至具有非易失性锁存器并可在关断时记住设置。

    DAC输入结构存在无数变化形式,本文将不一一介绍,但几乎所有都称为“双缓冲”。栓 缓冲DAC具有两组锁存器。数据最初锁存在第一级中,然后传输到第二级,如图8所示。 这种配置非常有用,具体有以下几种原因。

    图8:双缓冲DAC允许复杂输入结构和同步更新

    首先…
