hi,

I want to use 8 LTC2107 @ 204MSPS with synchronized data sampling.

Is there any extra requirements for schematic design other than the same sampling clock?

I noticed that LTC2107 doesn't have other special pins for synchronization.

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;
assign data95[2]=16'b00…

Hi,

I am planning to use LTC2107 on our boards with ARRIA 10 FPGA. Our Analog Inptu Range is 1.5 MHz to 190 MHz.

Now, my query is that whether I can use the following circuit for my entire range even though it recommends using from 100M to 250M:- 

hi, I am using the LTC2107, I hope to configure the ltc2017 by SPI using FPGA and Verilog. In PCB connecting PAR/SER pin to ground.  

     same verilog code  can be program the AD9510,AD9858,AD9520 except the register number and register content which correspond…

In datasheet LTC2107 ADC 2-Tone IMD Distortion is given with PGA = 0 condition only, Whereas we need the IMD distortion levels with PGA = 1 condition around frequency 141 to 170MHz input frequency at -7dBFS.

This is because we need the SFDR spec more…

I have some question on determining the IF sampling capability of ADC's :

I've checked the ADCs selection table for ADC > 10MSPS

• some ADC datasheets explicitly mention that the device is suitable for IF sampling, i.e : AD9461, LTC2195, ..…

Hi 

I need to convert a ±4.5V single ended signal to a differential signal for an ADC input (probably the LTC2107). Since the input Signal has a -3dB bandwidth of about 50MHz the ADA4945 in high power mode should be sufficient.

The Vocm is set to…
