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 Ω resistors to GND in parallel with L1, L2.
6 Jumping from 88 MHz to 108 MHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
7 For more detail on using tuned loads, see the Output Matching section.
8 Using 50 Ω resistors to VVCO, into a 50 Ω 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 REFIN for the
synthesizer; offset frequency = 1 kHz.
12 fREFIN = 10 MHz; fPFD = 200 kHz; N = 1000; loop B/W = 10 kHz.
13 fREFIN = 10 MHz; fPFD = 1 MHz; N = 120; loop B/W = 100 kHz.
14 The spurious signals are measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP 8562E Spectrum Analyzer. The Spectrum Analyzer provides the REFIN
for the synthesizer; fREFOUT = 10 MHz @ 0 dBm.
