Unless otherwise stated, these characteristics are guaranteed for VCO core power = 5 mA. L1, L2 = 270 nH, 470 resistors to GND in parallel with L1, L2.
6
Jumping from 88 MHz to 108 MHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.

Using 50 resistors to V
VCO
, into a 50 load.
9
The noise of the VCO is measured in open-loop conditions.
10
The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 log
N
(where
N
is the N divider value). The
phase noise figure of merit subtracts 10 log (PFD frequency).
11
The phase noise is measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP 8562E Spectrum Analyzer. The Spectrum Analyzer provides the REF
IN
for the
synthesizer; offset frequency = 1 kHz.
