NOTES

1Operating temperature range is as follows: B Version: –40

°C to +85°C.

2The B Chip speciﬁcations are given as typical values.

3This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the IF/RF input is divided down to a frequency that is

less than this value.

4V

DD1 = VDD2 = 3 V; For VDD1 = VDD2 = 5 V, use CMOS-compatible levels, TA = 25

°C.

5Guaranteed by design. Sample tested to ensure compliance.

6V

DD = 3 V; P = 16; RFIN = 900 MHz; IFIN = 540 MHz, TA = 25

°C.

7The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 logN (where N is the N divider value). See

TPC 16.

8The phase noise is measured with the EVAL-ADF4210/ADF4212/ADF4213EB Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the

REFIN for the synthesizer (fREFOUT = 10 MHz @ 0 dBm).

9f

REFIN = 10 MHz; fPFD = 200 kHz; Offset frequency = 1 kHz; fIF = 540 MHz; N = 2700; Loop B/W = 20 kHz.

10f

REFIN = 10 MHz; fPFD = 200 kHz; Offset frequency = 1 kHz; fRF = 900 MHz; N = 4500; Loop B/W = 20 kHz.

11Same conditions as listed in Note 10.

12f

REFIN = 10 MHz; fPFD = 200 kHz; Offset frequency = 1 kHz; fRF = 1750 MHz; N = 8750; Loop B/W = 20 kHz.

13f

REFIN = 10 MHz; fPFD = 10 kHz; Offset frequency = 200 Hz; fRF = 1750 MHz; N = 175000; Loop B/W = 1 kHz.

14f

REFIN = 10 MHz; fPFD = 1 MHz; Offset frequency = 1 kHz; fRF = 1960 MHz; N = 9800; Loop B/W = 20 kHz.

Speciﬁcations subject to change without notice.
