• ADF4156 start-up voltage

    Hello

    I'm a DFAE in Japan. The customer wants to start up ADF4156 at the lowest possible voltage due to his system issue.
    According to the specifications, it is 2.7V to 3.3V, but what is the voltage of VDD when the IC starts up? Is it 2V, 1V or any voltage…

  • RFinput for ADF4154, ADF4156

    Hi,

    I'm a DFAE in Japan. The customer is thinking of adopting ADF4154 or ADF4156, but he wants to use the input frequency at 78MHz. In this case, is it possible to operate at the low frequency if the slew rate is kept at 400V / µs?

    Regards,

  • RF sensitivity meaning in ADF4156 datasheet

    Regarding the ADF4156 datasheet, according to table 1, the RF IN (for single pin or for both pins combined??) require/s power between -10dBm to 0dBm.

    According to figure 5, it seems the RF power required is below -15dBm all over the usable range (I probably…

  • ADF4156快速锁定问题

    请教一个ADF4156的问题。ADF4156的文档说明:要使用Cycle Slip Reduction Mode来提高锁定速度“CSR cannot be used if the phase detector polarity is set to negative.“。控制宽带的VCO的使用需要加运放,这时如果把phase detector polarity set to negative,就不能用CSR功能。能否把极性设置为正,用两个运放反相的运放?一个做反相放大,一个做反相环路滤波器?

    谢谢…
