NOTES
Operating temperature range is as follows: B Version: –40°C to +85°C.
The B Chip specifications are given as typical values.

This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the RF input is divided down to a frequency
which is less than this value.

The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 logN (where N is the N divider value).

The phase noise is measured with the EVAL-ADF411XEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for
