• RE: SPI read issue with AD9204-80EBZ eval board

    Hi ManuR,

    Here are a few initial questions.

    • Do you have jumpers properly placed on J302. These are needed to connect the AD9204 to the SPI bus.
    • J301 is on the 3V side of the level shifters U301 and U302. Are your voltage levels appropriate?
    • I'm sure…
  • AD9204 sampling single ended DC signal, how to connect the analog front end

    I have a design that requires the use of AD9204 to sample a single ended DC signal, do not know how to connect analog front end circuit.

    The current design is to connect the AD9204 analog input AIN- to the GND, and the single ended DC signal is connected…

  • Input circuit of AD9204/9231

    Dear Sir/Madam,

    We have a question about AD9204 & AD9231 High Speed ADCs. (both BCPZ-40)

    We would like to know the analog input circuit which acquired the AC SPECIFICATIONS on the data sheet.

    There is specification at fin=200MHz.

  • RE: AD9204 SPI issues

    Hi Alon,

    I checked regarding question #2, and yes, the timing parameters tS and tH between CSB and SCLK also apply to stalling mode.

    Thank you.

  • AD9204 output data multiplexing

    The datasheet for the AD9204 mentions having the option of mulitplexing the output data but does not go into any detail on how to do this.  Can someone supply me with the specifics on how to go about doing this?

  • 使用ADA4938驱动AD9204的问题

    在AD9204的数据手册中推荐使用全差分放大器ADA4938来作为输入驱动,并且将ADC的Vcm输出连接到ADA4938的共模设置引脚。


    问题一:

    1、AD9204的共模输出电压Vcm是不是只有0.9V?(数据手册中没有给出该参数)

    2、ADA4938的输出共模电压最低只能设置到1.1V(高于0.9V)。

    所以如果使用数据手册中推荐的电路连接方式(ADA4938使用AD9204提供的共模电压Vcm),是不是存在问题?

    问题二:

    如果不使用ADC输出的共模电压,使用外部1.3V电压作为ADA4938的共模设置电压…

  • RE: Differntial Input impedance of AD9629-20

    Hi rgipps,

    The single Zeus (AD9609/29/49) S-Parameters are the same as the dual Zeus (AD9204/31/51) family. It has the same ADC core just reduced to one channel.

    Regards,

  • AD9608 Full Scale Input

    Hi,

    As AD9204 is pin-pin compatible with AD9608, could AD9608's full scale input also be set to 1Vpp?

    I saw the register description in AD9608 datasheet has the full scale adjust reg, but I cannot find any other inform in the datasheet:

  • AD9608 Interleaved Data Output Timing

    Hi,

    I think the datasheet of AD9608 made a mistake on the digital output timing of CMOS interleave mode:

    If the interleave mode is really working as above, how could it be helpful to reduce pin count? That I will lost CHA N-15, N-13, N-11,etc if only…

  • RE: QPSK receiver Design using ADRf6806

    Hi,

    If your bandwidth is +/- 16.896MHz, then a dual 10 bit ADC with a 80Msps sample rate should be sufficient for your design.  The AD9204 would be a low power solution used in many similar applications.  I am not an expert on  the baseband processing…
