NOTES
Operating temperature range is as follows: B Version: –40°C to +85°C.
The B Chip specifications are given as typical values.
3
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.

7
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).
8
The phase noise is measured with the EVAL-ADF411XEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for
the synthesizer (f
REFOUT
= 10 MHz @ 0 dBm). SYNC = 0; DLY = 0 (See Table III).
