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.

5Guaranteed by design. Sample tested to ensure compliance.

6P = 16; RF

IN = 900 MHz; IFIN = 540 MHz.

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).

8The phase noise is measured with the EVAL-ADF421XEB1 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.

11f

REFIN = 10 MHz; fPFD = 30 kHz; Offset frequency = 300 Hz; fRF = 836 MHz; N = 27867; Loop B/W = 3 kHz.

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 = 200 kHz; Offset frequency = 1 kHz; fRF = 1960 MHz; N = 9800; Loop B/W = 20 kHz.

Speciﬁcations subject to change without notice.
