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 These characteristics are guaranteed for VCO core power = 15 mA.
6 Jumping from 1.6 GHz to 1.95 GHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
7 Using 50 Ω resistors to VVCO, into a 50 Ω 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-xEB1Z Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for the
synthesizer; offset frequency = 1 kHz.
