• ADF4193 unlock

    Hi,recently our customer designing ADF4193 refer to Evaluation Board sch.However the frequency always unlock.

    Can you help support relative configure reference code? Thanks.

  • ADF4193 register map query

    I have a quick query regarding the ADF4193 register map. Unlike the ADF4351, the 4193 has registers of a differing number of bits (p.14 of D/S). However, I presume that as you write the control bits last due to the serial programming being MSB first that…

  • ADF4193 manual bandwidth register setting

    In the ADF4193 eval board software, there is a setting to lock the PLL into wide bandwidth mode, which was useful for us in debugging some stability issues with an external op-amp. Now that we have the board back, I don't see the register setting that…

  • Extending Tuning Voltage of ADF4193

    CP has an output voltage of 1.2V~Vp3-0.3V, but after adding an CMR voltage 3V, voltage range becomes 1.8V~Vp3-0.8V. How does this work? I feel confused and when designing circuits that extending VCO tuning voltage. Thank you!

  • ADF4193 Does Sim PLL predict integer boundary spurs

    Doing a  design with ADF4193 Does SimPLL account for integer boundary spurs?  Fref is 25MHz, Mod=250,  loop BW is 80KHz, operating from 2.45 GHz to 2,68GHz with a channel spacing of 100KHz.  I have done calcutations on a spread sheet for the integer boundary…

  • ADF4193宽带频率输出快跳锁定问题

    利用ADF4193作为鉴相器,输出频率带宽1500MHz(如1500--3000MHz输出,步进1MHZ)频率转换时间最快可达多少us?环路滤波器需加运算放大器,电路如何实现及如何仿真环路?

  • ADF4193锁定标准的问题,帮忙看一下,多谢

    你好,请教个关于本振的问题:

    ADF4193的锁定:从手册上看,当前向分频之后的频率和VCO输出频率分频之后两个频率差在一定范围之内,内部逻辑

    检测到连续几个脉冲之内在范围内,就判定为锁定,从手册上看是3ns,是不是可以这样理解:

    如果输入频率:10MHz,输出频率:400MHz,鉴相频率为10MHz

    这样鉴相周期就是:1/10MHz:100ns,如果差异在3ns,那么假定参考是精确的,那么输出经分频之后的周期就为97ns或者是103ns,这样考虑N分频输出频率就为

    412.37MHz或者388…
