• RE: LTC2185 LVDS Encode Drive

    equivalent circuit of encode inputs for LTC2185 show they are hi-Z

    this would mean that the 100ohm termination for the pecl/lvds drivers would need to be placed external to the LTC2185

  • ltc2107 or ltc2185 SPI program

    HI

       当用SPI配置LTC2017或者LTC2108的时候需要注意什么?

       因为我用fpga配置以上两个芯片,总是不能成功,而相同的主程序,配置ad9520,ad9510,ad9858等都可以。这些程序里面我只修改了相关的寄存器数量和相关寄存器内容,以下是寄存器的内容:

    assign data95[0]=16'b0000_0000_0000_0000;
    assign data95[1]=16'b0000_0000_1000_0000;

  • 你与实现LTC2185出色的线性度之间只差一个放大器

    今天版主要为大家介绍的是一对具有出色线性度的产品——LTC2185 和 ADA4927-1

    LTC2185 是一款16位、125 MSPS ADC,具有出色的噪声性能和线性度,同时每通道所需功耗仅为185 mW,非常适合要求严苛且需要出色交流性能的低功耗应用。这种性能的 ADC 需要配备高性能放大器,才能以保持其出色性能。ADA4927-1可满足LTC2185的线性度需求,同时功耗仅为215 mW。

    ADA4927是一款高速差动电流反馈型放大器。ADA4927-1 采用 ADI 公司的硅-锗工艺制造…

    让想起前阵子公众号里的那篇“相得益彰,ADC + 驱动器”,不过LTC2185只有16bit。

    不过设计思路值得参考的。
