• ADCLK946 series connection

    Hi,

    Using two ADCLK946's, I would like to series connection.

    I would like to connect the output of 1st ADCLK946 to the input of 2nd ADCLK946.

    Please let me know the circuit of termination in this case.

    Is the attached circuit correct?

  • ADCLK946作为AD9739的时钟驱动

    ADCLK946输出为LVPECL,是否可以直接给AD9739作为时钟驱动LVDS,在LVPECL转至LVDS电路设计上有需要注意的么?

    目前调试过程中,DAC失锁,怀疑时钟的输入幅度不满足要求,946的输出差分摆幅理论为1.6V,按道理是满足9739的时钟输入要求的。实测的相噪是满足要求的,但是目前尚未实测DAC时钟输入端的差分电平为多少。

  • RE: VCO fanout to 4 x 50ohm loads

    Use of an ADCLK946 would easily accomplish this goal. Connect the VCO output to the input of the ADCLK946 and the outputs to the various demodulators.

    The circuit on figure 17 of the ADCLK946 datasheet is the most suitable for the task you wish to accomplish…

  • RE: ADCLK925 sine wave input

    Hi tonyr,

    The E5052B RF IN port is already a 50ohm. So there is no need to terminate the ADCLK946 into a 50ohm and then plug that into the E5052B. You just lowered the load impedance for the ADCLK946 driver and the voltage of the clock signal seen by…

  • RE: ADF4350/1 & ADCLK846

    Hi Alon,

    Do you need LVDS outputs?  Typically ADCs benefit from the large swing and fast slew rate of an LVPECL driver.

    This circuit note shows an ADF4351 connected to the ADCLK948 and the resulting performance.

  • RE: ADF4350使用问题

    我看了AD9739芯片的datasheet,有张电路图直接将AD9739 与ADF4350连载了一起,直接用了,没有加类似于ADCLK946的时钟放大器,这是咋回事?而且datasheet说>2Vp-p是啥意思?
