The phase noise is measured with the EVAL-ADF4106EB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for

f
Operating temperature range (B Version) is –40°C to +85°C.
The BChip specifications are given as typical values.
Use a square wave for lower frequencies, below the mimimum stated.
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

Guaranteed by design. Sample tested to ensure compliance.

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