ADC板子设计

  1. what is ADCLK-positive and negative ?
  2. why AVDD and LVDD are equiquented with different capacities.?
  3. FPGA 92,91 - ADCLK+/-
  4. how to connect the lines of two adc chips to the FPGA board? what is the pin assignment?

  5. 普通模式的电压输出Vcm直接通过一个运放接给全差分运放作为ADC的输入数据。

  6. Fibre 是什么玩意？ 磁珠

  7. why in the original FPGA design the voltage of ADC input should be transferd to 2.5V , while by Jannik it is 3.3 V to the FPGA? 因为使用的fpga不同，电压不同
  8. why the Vcom1 and Vcom2 are seperated ? it's the same!
