File Size : 116 KB Manufacturer:TI Description: Operating temperature range is C40C to +85C. Guaranteed by design. Sample tested to ensure compliance. 3ICP is internally modified to maintain constant loop gain over the frequency range. 4TA = 25C; AVDD = DVDD = VVCO = 3.3 V; P = 32. 5These characteristics are guaranteed for VCO core power = 10 mA. 6Jumping from 1.0 GHz to 1.25 GHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz. 7Using 50 Ω resistors to VVCO, into a 50 Ω load. For tuned loads, see Output Matching section. 8The noise of the VCO is measured in open-loop conditions. 9The 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). 10The phase noise is measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for the synthesizer; offset frequency = 1 kHz. 11fREFIN = 10 MHz; fPFD = 200 kHz; N = 5000; Loop B/W = 10 kHz. 12fREFIN = 10 MHz; fPFD = 1 MHz; N = 1000; Loop B/W = 25 kHz. 13The spurious signals are measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for the synthesizer; fREFOUT = 10 MHz @ 0 dBm.
