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.
5
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 90 MHz to 108 MHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
7
8
Using 50 resistors to VVCO into a 50 load.
9
The noise of the VCO is measured in open-loop conditions. L1, L2 = 56 nH.
10
The phase noise is measured with the EV-ADF4360-9EB1Z evaluation board and the Agilent E5052A signal source analyzer.
11
fREFIN = 10 MHz; fPFD = 1 MHz; N = 360; loop B/W = 40 kHz. The normalized 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) and 10logfPFD. PNSYNTH = PNTOT 10logfPFD 20logN.
12
The jitter is measured with the EV-ADF4360-9EB1Z evaluation board and the Agilent E5052A signal source analyzer. A low noise TCXO provides the REFIN for the
synthesizer, and the jitter is measured over the instrument’s jitter measurement bandwidth. fREFIN = 10 MHz; fPFD = 1 MHz; N = 360; loop BW = 40 kHz, unless otherwise
noted.
13
The spurious signals are measured with the EV-ADF4360-9EB1Z evaluation board and the Agilent E5052A signal source analyzer. The spectrum analyzer provides the
REFIN for the synthesizer; fREFIN = 10 MHz @ 0 dBm. fREFIN = 10 MHz; fPFD = 1 MHz; N = 360; loop BW = 40 kHz.
