Pls help to clarify on the point for ADF4156; ADIsimPLL is supporting the
frequency of 102.2Mhz but data sheet is not covering this band (page 3.)


I just have a test with the ADIsimPLL v1.3. But I don't find the problem.
1) the ADIsimPLL can not support 102.2MHz with ADF4156
2) the ADIsimPLL can support 4.93GHz to 5.83GHz with ADF4108, I don't find the
BTW, in fact, ADF4156 can support a 102.2MHz. although in datasheet, it says RF
input should be 0.5GHz to 6GHz. But please note the test condition column. and
if you can have a high slew rate input, the input freqency could be lower than
