  • 关于analog公司ADC模块LTC2183的问题

    你好!
            我是浙江理工大学的学生陈洪强,在使用analog公司ADC模块LTC2183碰到一些问题,想咨询一下。
           我在公司网址www.analog.com/.../218543f.pdf的第14页,最右下角,看到这样一幅图,图片放在下面,这张图的输入信号为140MHz,采样频率为80Msps,以我个人现在的理解,这种情况下,AD采样出来信号有多个频率,分别为140-80=60MHz;80*2-140=20MHz;80*3-140=100MHz……说明采样后的频率分量有20M,60M,100M…
  • Digital Output Randomizer and Alternate Bit Polarity in DDR CMOS mode of LTC2183

    Hi 

    I will uses Digital Output Randomizer and Alternate Bit Polarity in  DDR CMOS mode of LTC2183.

    Does LTC2183 execute Digital Output Randomizer and Alternate Bit Polarity before changing from SDR(Single data rate) to DDR(Double data rate)?

  • LTC2183 CLKOUT timing afer first ENC input

    Hello

    I am FAE in Japanease distributor.

    Our customer uses LTC2183 with ENC=80MHz, SCK=2MHz.

    They writes data 02h to address 03h  for reset  by SPI after power on.

    Then they writes data 02h to address 03h for CMOS DDR mode setting by SPI .

    CLKOUT signal…
