1 Operating temperature range (B Version) is –40°C to +85°C.

2 The B Chip specifications are given as typical values.

3 Use a square wave for lower frequencies, below the minimum stated.

4 This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the RF input is divided down to a frequency that

is less than this value.

5 AVDD = DVDD = 3 V.

6 Guaranteed by design. Sample tested to ensure compliance.

7 TA = 25°C; AVDD = DVDD = 3 V; P = 32; RFIN = 7.0 GHz.

8 TA = 25°C; AVDD = DVDD = 3.3 V; R = 16383; A = 63; B = 891; P = 32; RFIN = 7.0 GHz.

9 The synthesizer 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).

10 The phase noise is measured with the EVAL-ADF4107EB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for the

synthesizer (fREFOUT = 10 MHz @ 0 dBm).

11 fREFIN = 10 MHz; fPFD = 200 kHz; Offset Frequency = 1 kHz; fRF = 900 MHz; N = 4500; Loop B/W = 20 kHz.

12 fREFIN = 10 MHz; fPFD = 200 kHz; Offset Frequency = 1 kHz; fRF = 6400 MHz; N = 32000; Loop B/W = 20 kHz.

13 fREFIN = 10 MHz; fPFD = 1 MHz; Offset Frequency = 1 kHz; fRF = 6400 MHz; N = 6400; Loop B/W = 100 kHz.
