• RE: ADF4007 frequency divider

    I have found additional information in the data sheet which I didn't see.  The 21k Ohm resistor does deque the capacitor but it did modify the biasing of the device by a very small amount.

    I am seeing an oscillation on the eval board at ~110MHz with…

    Hello,

    Using the ADF4007BCPZ as a Divider only, with programmable fix divide-by -8, -16, -32 or -64.

    We need an information regarding it’s Residual SSB Phase Noise Performance (not found in its data sheet).

  • 关于ADF4007的问题

    在测试ADF4007评估板(EVAL-ADF4007/4107EB1)时,发现有几个问题。

    1. 电源On/OFF的标识是否弄反了。

    2. datasheet中测试步骤中第六步中,”Apply 640MHz, -4 dBm signal to J1“,是否J1弄错,应该为J4

    3. 测试R couter或者N counter,发现Muxout端监测的信号发生畸变,并不是方波。测试结果见附件,其中CH1J3端,CH2T5端。这是否属于正常现象?

    最后有一个关于ADF4007芯片的问题…

  • ADF4007 (eval board) as phase detector and PLL

    I have an eval ADF4007 which I want to use to phase lock two lasers together. I'm testing it before getting to that feedback part, and I'm having an issue with error output from the CP/phase detector:
