• ADF4113HV initialized using the Initialization Latch Method

    Hi,

                    We are using a ADF4113HV, and previously thought it was a ADF4113 for one product.   In reading through the data sheet for the ADF4113HV, we discovered that the initialization latch is not touched or described.  The user guide for the ADF4113HV describes…

  • Comment on FAQ: Why use a PLL architecture that supports High Voltage VCOs?

    Dear App. Eng,

    I would like to use an ADF4113HV PLL in my DDS driven synth.

    I found in datasheet that Vp range is 13.5...16.5V. I have a max. 10V only.

    Q:

    Can I power the charge-pump by 10V? What kind of degradation is possible in PLL performance…

  • RE: Strange traveling spur problem seen in ADF4113HV

    There is no traveling spur from the ADF4113HV core - like you said, the traveling spur is a fractional-N problem. Your spur is probably coming from your reference, from the gain block, or from the VCO itself. Can you try isolating/bypassing these blocks…

  • RE: Mysterious behavior (ADF4350)

    Thanks for your replay

    I am using a TCXO 10MHz(FOX 926B) as a reference for my system. and I have used it in a different

    system with ADF4106 ADF4110 & ADF4113HV and it worked very nice without any problem

    but the problem appear here with ADF4350…

  • RE: Generation of LO using ADF4106 and V950ME08-LF

    The ADF4106 evaluation board only supports VCO tuning voltages up to 5.5 V. If you want to get tuning voltages up to 9.5 V you will need an active filter. Your active filter would have an op amp to gain the tuning voltage up to 9.5 V. You will need to…

  • RE: 锁相环常见问题解答

    楼主,附件有问题,解压不开。重传了一个。

  • 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。
