• FLo pin connection of ADF4212

    Customer seeks advice on FLo pin when using ADF4212.

    If fastlock mode is not used, how should the customer connect FLo pin ?

    Thanks.

  • RE: ADF4212 technical data..

    A Certificate of Compliance should be requested when parts are purchased. You need to go back to the point of purchase (authorized distributor or local ADI sales) to request one. If the parts were purchased through an unauthorized source then no Certificate…

  • RE: ADF4218L Power-Up Sequence

    I received some information back from ADI indicating that ADF4218L has the same “test bits” as the ADF4212 but they did not think the information above was necessary under normal operation.

    The way I interpreted this was that the references…

  • RE: 利用ADF4001实现10MHz锁相输出

    您好!

    1,是的

    2,Vp为电荷泵供电电压,其范围为AVdd~6V,如果压控电压最大为3V,那么供电电压最小为3V,但应注意应大于AVdd

    3,对于环路滤波器的设计,带宽和相位裕度请见附件内文档

    4,压控灵敏度为VCO的调谐参数,具体请参考VCO数据手册。
