Frequency range in component LTC6946IUFD-1


I wanted to ask if the LTC6946IUFD-1 component is capable of output frequencies of 2 GHz to 2.2 GHz since it is listed as having a range of 0.373 to 3.740 GHz but according to the datasheet this range is not continuous

I would love to know what the answer is

    That is correct, there is a frequency gap in all LTC6946 and LTC6948 /1 and /2 output divider states.  To achieve 2G to 2.2G you will need to look at the -2, -3 or -4 version.  By the way, the LTC6946 has recently been placed on the Not Recommended for New Designs list.  I would strongly recommend moving to the LTC6948, or one of the other ADI PLL/VCOs that supports your frequency range.
