1
Operating temperature range is 40°C to +85°C.
2
Guaranteed by design. Sample tested to ensure compliance.
3
ICP is internally modified to maintain constant loop gain over the frequency range.
4
TA = 25°C; AVDD = DVDD = VVCO = 3.3 V; P = 32.
5
For RF > 2 GHz, these characteristics are guaranteed only for VCO core power = 15 mA. For frequencies < 2 GHz, these characteristics are guaranteed only for VCO core
power = 20 mA.
6
Jumping from 2.0 GHz to 2.17 GHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
7
Using 50 resistors to VVCO into a 50 load. For tuned loads, see the Output Matching section.
8
The noise of the VCO is measured in open-loop conditions.
9
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).
10
The phase noise is measured with the EV-ADF4360-2EB1Z Evaluation Board and the HP8562E spectrum analyzer. The spectrum analyzer provides the REFIN for the
synthesizer; offset frequency = 1 kHz.
11
fREFIN = 10 MHz; fPFD = 200 kHz; N = 10000; Loop B/W = 10 kHz.
12
fREFIN = 10 MHz; fPFD = 1 MHz; N = 2000; Loop B/W = 25 kHz.
13
The spurious signals are measured with the EV-ADF4360-2EB1Z Evaluation Board and the HP8562E spectrum analyzer. The spectrum analyzer provides the REFIN for
the synthesizer; fREFOUT = 10 MHz @ 0 dBm.
