1The B chip specifications are given as typical values.
2This 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.
3AC coupling ensures AVDD/2 bias. See Figure 33 for a typical circuit.
4Guaranteed by design.
5 TA = 25°C; AVDD = DVDD = 3 V; P = 16; SYNC = 0; DLY = 0; RFIN for ADF4110 = 540 MHz; RFIN for ADF4111, ADF4112, ADF4113 = 900 MHz.
6 The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO, PNTOT, and subtracting 20logN (where N is the N divider
value) and 10logFPFD: PNSYNTH = PNTOT – 10logFPFD – 20logN.
7 The phase noise is measured with the EVAL-ADF411xEB1 evaluation board and the HP8562E spectrum analyzer. The spectrum analyzer provides the REFIN for the
synthesizer (fREFOUT = 10 MHz @ 0 dBm). SYNC = 0; DLY = 0 (Table 7).
8 fREFIN = 10 MHz; fPFD = 200 kHz; offset frequency = 1 kHz; fRF = 540 MHz; N = 2700; loop B/W = 20 kHz.
9 fREFIN = 10 MHz; fPFD = 200 kHz; offset frequency = 1 kHz; fRF = 900 MHz; N = 4500; loop B/W = 20 kHz.
10 fREFIN = 10 MHz; fPFD = 30 kHz; offset frequency = 300 Hz; fRF = 836 MHz; N = 27867; loop B/W = 3 kHz.
11 fREFIN = 10 MHz; fPFD = 200 kHz; offset frequency = 1 kHz; fRF = 1750 MHz; N = 8750; loop B/W = 20 kHz
12 fREFIN = 10 MHz; fPFD = 10 kHz; offset frequency = 200 Hz; fRF = 1750 MHz; N = 175000; loop B/W = 1 kHz.
13 fREFIN = 10 MHz; fPFD = 200 kHz; offset frequency = 1 kHz; fRF = 1960 MHz; N = 9800; loop B/W = 20 kHz.
14 fREFIN = 10 MHz; fPFD = 1 MHz; offset frequency = 1 kHz; fRF = 3100 MHz; N = 3100; loop B/W = 20 kHz.
