1 Operating temperature range (B Version) is –40°C to +85°C.
2 The B chip specifications are given as typical values.
3 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.
4 AVDD = DVDD = 3 V.
5 AC coupling ensures AVDD/2 bias.
6 Guaranteed by design. Sample tested to ensure compliance.
7 TA = 25°C; AVDD = DVDD = 3 V; P = 16; RFIN = 900 MHz.
8 TA = 25°C; AVDD = DVDD = 3 V; P = 16; RFIN = 2.0 GHz.
9 TA = 25°C; AVDD = DVDD = 3 V; P = 32; RFIN = 6.0 GHz.
10 TA = 25°C; AVDD = DVDD = 3.3 V; R = 16383; A = 63; B = 891; P = 32; RFIN = 6.0 GHz.
11 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) and 10 log FPFD. PNSYNTH = PNTOT − 10 log FPFD − 20 log N.
12 The PLL phase noise is composed of 1/f (flicker) noise plus the normalized PLL noise floor. The formula for calculating the 1/f noise contribution at an RF frequency, fRF,
and at a frequency offset, f, is given by PN = PN1_f + 10 log(10 kHz/f) + 20 log(fRF/1 GHz). Both the normalized phase noise floor and flicker noise are modeled in
ADIsimPLL.
13 The phase noise is measured with the EV-ADF4106SD1Z evaluation board and the Agilent E4440A Spectrum Analyzer. The spectrum analyzer provides the REFIN for
the synthesizer (fREFOUT = 10 MHz @ 0 dBm).
14 fREFIN = 10 MHz; fPFD = 200 kHz; Offset Frequency = 1 kHz; fRF = 900 MHz; N = 4500; Loop B/W = 20 kHz.
15 fREFIN = 10 MHz; fPFD = 200 kHz; Offset Frequency = 1 kHz; fRF = 5800 MHz; N = 29000; Loop B/W = 20 kHz.
16 fREFIN = 10 MHz; fPFD = 1 MHz; Offset Frequency = 1 kHz; fRF = 5800 MHz; N = 5800; Loop B/W = 100 kHz.
TIMING CHARACTERISITICS
AVDD = DVDD = 3 V ± 10%, AVDD ≤ VP ≤ 5.5 V, AGND = DGND = CPGND = 0 V, RSET = 5.1 kΩ, dBm referred to 50 Ω, TA = TMAX to TMIN,
unless otherwise noted.
