• LTC2107 PSRR

    There is no information about the power-supply requirement for the LTC2107 in the datasheet. How does noise from the supply-rail propagate to the signal? As en axample: There may be noise from different channel on the power rail, from the current drawn…

  • Synchronization of multiple LTC2107 ADCs

    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.

    best reg…

    There might be better transformers, but this configuration will have 1-2dB of loss.

  • 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;
    assign data95[2]=16'b00…

  • RE: ltc2107 or ltc2185 SPI program problem

    I don't understand the question. Do you want to use the same code to program two different parts?  The LTC2107 and LTC2185 have different SPI commands and registers. There is some overlap but quite a few of the registers are completely different.  Better…

  • LTC2107 ADC 2-Tone IMD Distortion with PGA = 1 condition

    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…

  • ADA4945 SE-DIFF conversion simulation

    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…

  • RE: DC2266A 16-Bit, 210Msps ADC FMC reference design for Zedboard

    Hi Andrei,

    The  LTC2107 is nice bit of silicone, why there are no plans to support it?

    LT  goodies not first class citizens?

  • RE: High speed ADC input frequency range

    Hello Joe,

    Every ADC can sample 0 (DC) to whatever frequency is listed in the datasheet as the highest frequency. Any of the ADCs below will be able to fit your application

    Thanks

  • how do I know if an ADC is suitable for IF sampling, i.e AD9653 or AD9655?

    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, ..…
