• RE: ADF4213 Datasheet Issues

    Hi Tim,

    Both RF and IF counters are 6-bit for A-counter and 12-bit for B-Counter.The timing diagram is in error, it should show DB23 as MSB.

    You might want to look at ADF4218L or ADF4212L if you need a dual PLL. These are newer lower power devices.…

  • ADF4218L Power-Up Sequence

    Our team is planning on using the ADF4218L on one of our products. Reading through the AskTheCommunity questions there are references on the ADF4212L about clearing all bits in the IF R Counter Latch register and RF R Counter Latch register immediately…

  • ADF4218L Powering Up

    I was going over the ADF4218L datasheet and found this line "On first applying power to the ADF4217L family, it needs four writes (one each to the R counter latch and the AB counter latch
    for both RF1 and RF2 side) for the output to become active…

  • 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。
